Venice 3800+

benktlottie · **Venice 3800+ -** 04-29-2005, 21:47 | posts: 1,046 | Location: Wiltshire, UK

Hi people,

Thought I would share my first impressions of my new Venice 3800 chip with fellow Guru's ! The chip ID is: -

ADA3800DAA4BP -- CBBLE -- 0513 CPBW -- 1232892D50659

Well...I have mixed feelings, with a little bit of frustration chucked in, to be honest.

Before I tell you what I have found, this is what I know (through weeks of testing ang use) what my rig can do. With a 3200 Winnie, I can set the FSB @ 265 with the multiplier set to 10 and RAM timings of 2.2.2.11 (with 3.6v, and 2 fans keeping the RAM cool). With HTT set to 5, so 2000. Stable. Will run Prime for hours and will benchmark and play games with no problems. Temps were around 23 idle, and 35-40 under full load using a Zalman Reserator water cooler. Voltage was set to 1.5v with 104% additional volts. With my 3800 Newcastle, exactly the same setting, but with the voltage set to 1.55 with 104%, sometimes with 110%.

When I first got the Venice this morning, I started to Prime it with 250x11 = 2750mhz. Went to work, and had my brother check it every 30 minutes. Ran like a dream, to begin wit, temps between 23-27 degrees C. 3 hours into testing temps went above 30 for the first time. 4 hours and 36 minutes, test executed. I was well happy. To me, 4 and a half hour Priming is fine. THIS WAS ON DEFAULT VOLTAGE !!! Got home from work, ran a 3dmark03 bench, made it all the way through, nice score, 22656.

So...decided to really get to work on this baby !!! Set the FSB to 260, multi set to 11 = 2860mhz. Blue screen. OK, so...more volts ! Set it to 1.45v with 103% additional volts. Blue screen. OK, so set it to 1.45v. with 110% additional. Booted into Windows. Ran a 3dmark03 benchmark...middle of test 2, lock up ! Damn, it was looking promising too score wise ! ;-)

Anyway, hours later of trying different volatges, different HTT's, different combinations of FSB's and Multis, I have a theroy on this chip.

The memory controller isnt all that it is made out to be, and also, this chip requires A LOT of VOLTS to maintain a high speed of over 2800mhz. And it can get warm.

I feel that I know my rig and motherboard very well (look at my specs to the right) and I have been clocking for a while now using the Zalman Reserator. Its a good piece of kit. But what concerns me is the amount of volts that the chip requires for a 2800mhz speed. I have so far found (the amount of reboots has driven me insane this evening) is that if the mutli is left on 12, the chip seems to be more stable. I am currently running it @ 240x12 = 2880mhz, HTT set to 5. I have run an Aquamark benchmark, and made it all the way through !!! Scored 93000+ by the way ! :-) Temps seem to be steady at 28-30 degrees C, but I am having to put 1.64 volts through it !!! Which I think is a lot...

I suppose I should be happy that I can work away using a processor @ 2880mhz, but I feel a little bit gutted !!! I really though I would be able to benchmark properly @ at least 2900mhz with less volts.

Has anyone else got one of this batch ? If so, please let me know your thoughts and/or settings regarding the performance you have reached. If anyone has any ideas that will help my sanity and increase stability, please share them.

I'll post any further results/findings as I achieve them

Dear god man, that's one heck of a system you've built yourself there

Very nice. Let us know how it comes along

i'd be interested to know how that monster runs 2001...

BeMyMonkey · 04-30-2005, 05:50 | posts: 1,844 | Location: Aachen, Germany

doesn't running the htt over 1000 mhz cause instability?

bit sad to hear the results though... i was thinking about getting one of those...

Try your HTT multiplier on 4 or even 3. It has been proven that total HTT has very little to do w/ performance\bandwidth. Also try your voltage on 1.35*123%. That seems to be working for some.

Really appreciate the support and good advice chaps. I have tried the following this morning: -

TEST SETUP: -

255x11=2805mhz
HTTx5
1.45v + 110%
RAM @ 2.2.2.11 @ 3.6v
PCI-x Frequency @ 105%
GT's @ 430/1134

Results: -

3Dmark01 - 30669
3Dmark03 - 23140
Aquamark - 94058

TEST SETUP: -

260x11 = 2860mhz
HTTx3
1.35v + 123%
RAM @ 2.2.2.11 @ 3.6v
PCI-x Frequesncy @ 105%
GT's @ 430/1134

Results: -

3Dmark01 - DID NOT COMPLETE - FAILED TEST 13 !!!
3Dmark03 - 23171
Aquamark - 95242 (NEW RECORD !)

TEST SETUP: -

265x11 = 2915mhz
HTTx3
1.35v + 123%
RAM @ 2.2.2.11 @ 3.6v
PCI-x Frequency @ 105%
GT's @ 430/1134

Results: -

3Dmark01 - FAILED FIRST TEST
3Dmark03 - DID NOT START
Aquamark - DID NOT START

AS you can see, quite stable @ 2860mhz, but the moment I go over 2900mhz, no benchmarks at all ! For everyday use, 2915mhz is fine. I can surf, listen to music, watch videos etc. I just tried SUPER PI for a laughand @ 2915mhz, It does 128k in 3 seconds and 256 in 7 seconds but it errors after 8 loops @ 512k !!! So, it aint that stable, but definately usable !

Temps are currently 27 IDLE

Any further idea appreciated, and I'll report back any further finding. Thanks for again for the advise.

Not stable but usable? What good is 2915Mhz if it's not working properly...

I really don't understand why would you want a fast but unstable machine - it's an accident waiting to happen (major data corruption on the way).

He He ! I see your point ! But...she's now been Priming for just under an hour and hasnt died yet...

What I meant was that she doesnt seem to want to benchmark at this speed. For daily use, she appears to be fine @ 2910mhz. I'm just a speed freak, who wants to get his processor running as fast as possible. Plus, data corruptions dont really worry me, she's purely a benchmarking/gaming machine, with no important data on. I have an image which I can restore on her if she corrupts (which she does sometimes) in 5 minutes. And, the important machines in the house arn't overclocked or benched, I aint brave enough to do that on the server we have here !!!

Still priming...thats just over an hour now. Spooky...

benktlottie · 04-30-2005, 12:26 | posts: 1,046 | Location: Wiltshire, UK

Shes hasnt failed Prime now for an hour and a half. Just stopped it as I wasnt to do other things on the machine ! Trying out 243x12 = 2915mhz, HTT x3 with all the same setting as before. Try and take some of the onus off the mem controller.

G L · 04-30-2005, 18:08 | posts: 10,261 | Location: San Ramon, California

Hah, I need 1.6v to get 2400 MHz with my winchester. As for getting warm, that may be our friend power leakage. Apparently heat increased much less linearly at .09 micron then before, so really maxing out the speed could cause it to really heat up.

benktlottie · 05-01-2005, 12:39 | posts: 1,046 | Location: Wiltshire, UK

After spending at least 15 hours messing around with this yesterday, and another 4 hours already today, I think I've found the sweetspots...

For general everyday use, that runs SUPER PI, best setting for me is....................240x12 = 2880mhz @ 1.554v, HTTx5, RAM @ 2.2.2.5 @ 3.6v using 310P BIOS. Runs fast and smooth and doesnt BSOD or crash/hang.

For benchmarking and games............255x11 @ 1.64v, HTTx3, RAM @ 2.2.2.11 @ 3.6v using 310P BIOS. Occasional hangs during benching. Also runs SUPER PI, and will PRIME for nearly 2 hours.

I think that I will give up for a week or 2, to leave the AS5 thermal paste and the processor to burn in before trying benchmarks again. I must admit, I'm happy with 2880mhz for daily use.

Thank for everyone advice, if anyone has anymore, please post...

lol, odd. you run a machine that regularly corrupts? odd, odd, odd... is it worth it?

other stability programs to run are superPI, 3dmark03 and 3dmark05, and folding(if folding errors out your machine is unstable).

Absoutely, the buzz I get from pushing the hardware. I also just love fiddling with the BIOS. I corrupt her registry a lot. I work in IT during the day, and bring work home. I test applications, and things clash. I may test 10 applications a day on her when I'm involved with XP rollouts and testing. Plus, I love breaking her and then fixing her. I know it sounds odd, odd, odd

Cool, can I get those off that thing called the internet ? I heard its on today...

i don't know about this thing called the internet. but you can get those on the interweb.

We've had them in the UK for over a week now. They really are very good. As I put in previous posts, they are certainley worth, if not a little bit frustrating !

Just installed Win 64 bit this afternoon, she seems to react very well with that operating system....

Tom F · 05-01-2005, 23:48 | posts: 2,640 | Location: Gloucesterestershire

cool you got it all working now mate

i'd love to have computer with that much power...

so are you keeping it at the speeds it's at currenlty or going to try to push it even faster?

EnemyOmen · 05-02-2005, 01:37 | posts: 3,340 | Location: Evansville, IN

the 3800+ vience has been out in US for at LEAST 2 days now.

If i had the money id probably buy one and OC it. but im quite happy with my 3000+ Winnie @ 2.5ghz

benktlottie · 05-03-2005, 18:03 | posts: 1,046 | Location: Wiltshire, UK

Update on what I' m running at now.

Was fiddling with the memory timings today. As I have some old school BH5 memory, thought I would try 1.5-2-2-6 for a luagh. Cranked the FSB upto 255, multi @ 11 so @ 2805mhz. Volts were set to 1.4v + 113%

To my amazement, shes been fine ! Even ran a benchmark or 2...Ive never been able to run my memory @ 1.5CAS, but today, no problems ! Perhaps the memory controller on this Venice core is improved. In theroy, if I put enough volts through the BH5, CAS1.5 is possible, and I have tried, just never been able to boot up.

I am learning the Venice is a great core...San Diego 3700 was released in the UK today via overclockers so may get one of those and compare these 2 awesome chips !

omarmakki · 05-03-2005, 19:57 | posts: 4,080 | Location: Egypt

the only difference between the san diego and the venice cores is that the san diego has 1mb l2 cache while the venice has only 512kb l2 cache...

benktlottie · *Last edited by benktlottie; 05-04-2005 at 00:10.*

Heres a screenshot of the CAS1.5 and what shes being overclocked to right now !

first time I've submitted an image. hence why previous thread was blank...

Lostfaith · 05-04-2005, 01:35 | posts: 545 | Location: Tropical Sweet Caribbean

I'm also planning on getting me one of those (in process of getting the DFi ultra-d).

I want to know what the highest stable OC (superpi 32m/8hours prime95 torture) you got for the cpu (cpu-oc, without ram/mobo factoring in) with and without extra voltage.

could you try that for me? genuinely interested where the cpu ceiling is (unovervolted).

oh yeah, good luck!!!

Results so far for you !

Ran it @ 2750mhz (11x250) @ default volts of 1.4v overnight (RAM at 2.2.2.11, v3.6, which is my favourite setting), and after 7hrs and 36 mins, the test failed. My wife had set the heating to go on @ 7am today, and the office dorr was shut. It was like a bloody sauna in here when I got up !!! So, I would suggest that heat was a factor there.

PRIME ran it for 4 hours 10 minutes this morning/afterrnon @ 260x11 = 2805 @ default volts of 1.4 (RAM again set to 2.2.2.11 @ 3.6v)

I will run some superpi later today.

Are there any more tests you would like me run m8 ?
