The calculator is a waste of time it abides by the clock generator which really doesn't matter. Don't let the calculator get u confused. Just have a standard increment of 25mhz. so if u don't want 2000 settle for 1975 as it will round up automatically to the closest clock in the clock generator which abides by the general rule of 25.

The 550 Ti is an ULTRA LOW Power GPU so even at 1.125v and 1000mhz it hits like 50C under load and fans are always quiet...

You won't hear any more fan noise it'll be super quiet so don't worry.

Set to 2000 as i said before for 1000mhz and 2100-2200mhz on memory and don't touch the memory latency parameters.

Just as an idea u can go to EBAY and search GR23P it's the dell oem GTX 460 1gb DDR5 @ 256bit - It'll eat the 550 Ti for breakfast at stock clocks. Push to 900mhz core, 1800mhz shader, 1800mhz memory at 1.125v and it's well beyond running 2 550 Ti's in SLI at 1000Mhz a piece. Trust me I tested it.

The special GR23P has One, yes that's right. One PCI-E power 6-pin so it uses less than 125W just like the 550 Ti.

The GR23P is $85 Shipped and is the best gpu for the money on the planet.

A month ago there was a lot for sale. I have been advocating them for quite some time, looks like there isn't much. Search where ever u can the GR23P - It's an insanely awesome gpu. I ran the best Nvidia Demo on it meant to only run on the Titan with two of these in SLI at 900Mhz and was getting 25fps, do that same test on two GTX 470's at 835mhz a piece and I'm getting 35fps. The 460's may hit 75C under load at 900mhz but the performance is awesome. They handle 800mhz core clock at 950mv by stock and hit like 50C under load.

Good luck.

ok, that explains a lot
a GTX 460 is a power hog, and i can run my CPU at 4.2GHz stable and a phenom II drinks power at high clock speeds like that i don't want to have to get a 650W PSU which would eat any saving up
If i wanted to get a new GPU i would probably go for a 650 TI boost and sell my 550 TI which i got for $67 after rebate

furmark can push this GPU to 67C if i don't touch the fan speed, the default fan curve on MSI afterburner keeps it at 60-62C during that test
furmark actually gets it almost 5C hotter than heaven 4.0
in my old case with a side fan on it the max heaven temp was 55C and the fan speed stays at 30% until 60-61C, hoping getting a bottom fan for this case will drop the temps to keep the fan speed at 30%, when ever newegg sends me one of those 20% case fans coupons

since my stock config is 910MHz do i add 25 increments to that or do i add that to reference 900MHz

If your reference is 910 the shader will be 1820. I abide by steps of 25 always so I'd change it to 1850 for 925, or 1900 for 950, or 1950 for 975 core clock.

The pci-e slot at 16x gives 75 watts. One 6-pin pci-e power gives 75W, so that's a total of 125w.

The 550 Ti has the slot (75w) and the 1 6-pin pci-e (75w) so it uses less than 125w.

The GR23P has the slot (75w) and the 1 6-pin pci-e (75w) so it uses less than 125w.

The GTX 460 GR23P has one 6-pin so it uses less than 125W. It also has the glorious 256 bit GDDR5 video memory running at 1800mhz. So when it comes down to it, the GR23P is getting more work done while using the same wattage as the 550 Ti. It also uses less power than the 650 Ti Boost with it's 2 x 6-pin pci-e power so it can use up to 225 watts which means more heat.

If you want more gpu performance rely on the memory bit specification over all else. If you get a 650 Ti boost your upgrading from 192 bit gddr5 to 192 bit gddr5. Memory bit means everything because it's the data channel communicating data between the powerful gpu core and the memory. The higher the bit the faster the communication between the gpu core and the memory. You speed up the bit, you therefore speed up the gpu core. The gpu core is always limited by the speed at which the memory can communicate with the core.

For instance math explains it all even know we may all think the 650 Ti boost is better sure it's core is of not only of higher performance than the 460 but runs cooler. However the core is not as important as the memory bit channel bottleneck.

256 bit is 33.33% faster than 192 bit if the core will permit the increase.
384 bit is 50.00% faster than 256 bit if the core will permit the increase.

192 bit has a maximum potential of 2.23517e-8 Gigabytes
256 bit has a maximum potential of 2.98023e-8 Gigabytes
384 bit has a maximum potential of 4.47035e-8 Gigabytes

The GTX 260 and GTX 280

GTX 260's 448 bit had a maximum potential of 5.21541e-8 Gigabytes
GTX 280's 512 bit had a maximum potential of 5.96046e-8 Gigabytes

I would always use MSI or EVGA to dial in the temps. Use a profile from 0C 0% to 75C 100%. In 1 linear slope to update every 1000ms and hyst. to 0 and force update at interval.

Send me the bios.rom and I'll configure it to optimum.

Make sure the fan in the built in profile is set to 40% min to 100% max but 25% min is okay to 100% fan. If the bios doesn't allow past 70% it will never go beyond 70%. Meaning you have to change the bios to allow 100% or it will only be able to reach 70% and cause overheating.

Set 3, 4, 11 to 2000 and 5 to 2075 (which may be unstable so stick to an even number of 2050) then go to the voltage and set P15 to 1.125v and don't rely on Furmark, that's a sure way to fry your card. Use games or benchmarks see if it'll run through 3dmark11 and your golden. 3dmark11 stresses the gpu like a game would so you can rest assured all games will be stable.

In regards to GPU's and if your willing and can find it, there is a super special rare version of the GTX 660 which is OEM only and has 256 bit memory as well as 2GB of GDDR5 with the insane performance of the GTX 760 2GB GDDR5. It's actually probably the same as the 760 because it has the same performance.

I send it via PM,BTW when i said it was unstable i was using MSI afterburner to test it before flashing
is furmark a reliable way to test stability?

Thanks and cool. I sent it back. Just ask me and I'll tell u what is a known stable clock. I always test in 3dmark11 as it's a good indicator or the best indicator for stability. If you notice atifacts but it passes, it's unstable. Set that fan slope profile I said first. I would never use furmark or any stress testing app as it'll fry your card. Always set vsync to keep the gpu under 99% utilization or your more likely to become unstable.

If your case has a 120mm fan in the front, make it suck air in, so it blows right over the back of the gpu where the voltage regulators are. If your hard drive is in the way, make a clear clean path so no wires at all are in the way. I recommend setting the fan to full speed to because the GTX 550 Ti has no vreg heatsink so the vregs get very hot by stock and much hotter overclocked. Yet they seem to run stable without any airflow over the voltage regulators at 1000mhz @ 1.125v.

Let me know and if u have any questions I'm happy to help.

i have a 120 and 140 mm fan intakes and exhaust, i want to get 2 more 140mm intakes and replace the 120mm
2 cooler master sickle flow and 2 140mm fractal fans one of each for intakes and exhaust
i am a wire management freak, there is not a single wire in the way of any airflow or the view of any parts for that matter

i have not managed to get anything to make a artifact, just crash something
i will use heaven 4 and 3dmark to check stability, any others i should use?
i linked a picture earlier i circled part of my GPU is that a HS on the voltage regulator?

Use only 3dmark11 only once maybe twice but once is enough, if it passes your golden. Don't run it over and over just go play your favorite game because thats the ultimate test is time. Play as long as you can.

See the heatsink at the back? That's the vregs... Most don't have that heatsink.



At the back all those little chips are voltage regulators and they all hit 100C regularly under load on stock clocks. If they approach 200C stability will be at stake. Although it doesn't seem to get that hot and runs stable at 1.125v and 1000mhz without the heatsink.

i do have a heat sysc in that location, not as big as that, maybe 1/4 to 1/3 that size, guessing that was not a 550 ti and was a higher end card with more regulators on it
edit:ok that was a 550 TI, guess my card only has a heat sync on the 1st few regulators that do the most work

Well that's a bit odd, they all do the most work since they are all there to handle a division of the power coming in which is in the 125 watt realm. So basically you have 15 regulators so you take your total possible consumption divided by 15, so 125 divided by 15 equals 8.3 watts per regulator. That means that 8.3 watts converted to Celsius heat units per minute is 0.26* Celsius per minute. So that means that each one of these in 10 hours at max load will see 156* Celsius without any ambient and without any dissipation. In 5 hours just 78* Celsius per regulator but thats not including the heat generated by not only the gpu core but also the super hot memory chips on the pcb. So we could easily see in the 100*+ Celsius. On higher end gpu's there are more handling more power etc.

If you don't have any thermal paste, I would recommend you pick some up on ebay. The very large long lasting tube of 25 grams Arctic Silver Ceramique 2. Because it costs $7.44 shipped and keeps temps very low as it's very effective. Not only that but you don't have to worry about spill over because it's not electrically conductive, only very thermally conductive.

http://www.ebay.com/itm/Arctic-Silve...item35c9925dde

I think this is your gpu


Also, When you re-paste this gpu add and spread the layer by finger across this whole surface. Very thin layer enough to transfer heat and not spill over much under compression.

Thats cool yeah can't see it but I can see a little, looks like a nice one. They should run cooler and handle the 1ghz and 1.125v without issue.

you probably are not seeing a little, that is the entire thing, it appears to only cover the area near the power plug on the card
i could see it only covering 1/2 of one of the regulators
the push pin spring in there is where the HS ends
you would think they would have put one to cover all of them if they are going to put one on there, maybe the TOP and Ultimate versions have bigger ones on them
i tested the OC in msi afterburner in valley, heaven, 3dmark11, alien vs predator benchmarks without issue
just seems strange to me that the calculator says 4 and 11 should be 2105 while you say 2000 and following the pattern ASUS used on there OCs setting 4/11 to what the calc says -5 for 2100

and get finger oils in the paste, nty
GPUs don't have that cover like a CPU does it? so you cant just use hte grain of rice method, correct?
i guess one of those disposable rubber gloves would work

EVGA OSD will display what the driver runs at. Refer to GPU-Z sensor data to get the clock the clock generator is producing. As the clock entered will be auto-corrected by the clock generator.

Don't worry about the calculator because all it does is give u the bumped clocks which do nothing more than require more voltage. Just do it the way I do it to minimize the voltage requirement since the clock generator does the calculations fermi calculator would do automatically.

It should be 1000Mhz core and 2000Mhz shader, as well as 2052Mhz memory. How are you flashing the gpu bios? It needs to be done in nvflash so it will be done the right way and report correctly.

Do re-paste anything in terms of cores, just put a dot big enough that you know for sure that with your index finger you can spread over the whole entire chip. The 550 Ti has that outer lip which needs paste too since it'll give more contact surface to transfer heat meaning lower temps than stock. Don't use a glove use your bare skin with Arcrtic Silver Ceramique 2 since it's ceramic. To re-paste the voltage regulators, remove the thermal interface material from the heatsink and clean the voltage regulators and heatsink spotless. Then apply a thin layer across the entire contact surface of the voltage regulator heatsink to get 25-45% better heat transfer, meaning lower vreg temps for improved stability. With that vreg heatsink you have we could push to 1050-1100 with additional volts if u re-paste the vregs like i said.

From what you said it's only covering half, pick up some copper heatsinks and add them manually to all the voltage regulators, or find a big copper one to cover them all and 1-2 small ones to cover the others. That's the only way to extend the life of the card indefinitely and push the clocks into the extreme realm.

Good luck

Okay since your on linux. That's cool it'll report whatever it sees could be wrong could be right. Use GPU-Z to be 100% sure and update to the latest nvidia drivers.

To Stress test one run of 3dmark11 is sufficient. Then game it up on your favorite games for hours to be sure.

What are your idle/ load temps in Celsius?

Your thoughts on the increase in performance? I found that 1000mhz on the 550 Ti made a world of difference in frame rate could be as much as 20 fps faster than stock.

Sorry for using this old topic but i have a problem, maybe someone can help me...

I have some strange throttling while playing older games souch as cs 1.6, Rise of nations etc...

Those games become choppy and laggy while playing because gpu ist working at full capacity. When switch to desktop, lag continues untill i run some furmark or something similar that awake the card. Tried everything driver/other software solutions but it is not woking..

So i think maximising the bios clocks of 2d and 3d performance will fix the problem..

Can you help me?
