I have tried several different configurations and I am unable to get this RAM to run at its advertised specs. Any ideas? Several reviews on Newegg state that this ram runs as advertised on the M4A89TD, which I have. I left everything on AUTO except: DRAM Frequency = DDR3-1600 tCL = 7 tRCD = 7 tRD = 7 tRAS = 24 tRC = 34 Command Rate 2T DRAM Voltage = 1.6V The QVL for my motherboard supports this ram at the advertised timings, but the DRAM Voltage is 1.65V I get BSOD after several minutes at 1.6V and Windows will not boot when at 1.65V Any suggestions? Do I need to change any other values in the BIOS? Thanks!
Loosen up the timings a bit, 8-8-8, see if they run. This story probably ends with you sending them back for a new set.
So I reset the BIOS to default settings and figured I'd e-mail G.Skill and see what they say. In the mean time, I thought I would play some Starcraft II and about 10 minutes in, BSOD and my computer restarted :bang: Looks like this new computer will have to sit for however long it takes to get this memory issue sorted out. I don't understand why this memory won't work when it's listed specifically in the QVL for my motherboard, even at default settings, let alone advertised specs. Several reviewers on Newegg have stated this memory works fine with their setup using the same combination. Could it be anything else? My temps are all fine and nothingis OC'd.
I just registered and got a quick response from the GSKILL Techs so I'll try his recommendations at lunch or after work. If that doesn't work, I've already ordered a DDR3-1333 set from Newegg to try and if that works better, I'll just send the DDR3-1600 back. As for the manual, I've been looking through it quite a bit to figure out how to use the Turbo Unlocker and the Turbo Key II settings, but it seems to me that the Turbo Unlocker doesn't do anything for my CPU and the Turbo Key II only gives me about 100Mhz OC from stock, does this sound normal for OEM HSF? Thanks for the input guys.
Mmm.. is the tRC value at fault here..? according to http://www.techpowerup.com/printarticle.php?id=131 'tRC Timing: Row Cycle Time. The minimum time in cycles it takes a row to complete a full cycle. This can be determined by; tRC = tRAS + tRP. If this is set too short it can cause corruption of data and if it is to high, it will cause a loss in performance, but increase stability.' So I ask have you tried to run the ram with a tRC = 31 tRD = 7 + tRAS = 24 = tRC = 31 I realise that the article says that if higher it should be more stable, but maybe that was back when that article was written.
Update! A big thanks to the GSkill techs... He suggested setting the timings to 7-7-7-24 1.65V @ DDR3-1600 as advertised with the rest on AUTO and raise the CPU/NB .1V... played about half an hour of SCII last night, ran a couple benchmarks and no problems! Now I've got an extra set of CL7 DDR3-1333 that I need to sell to a friend or something since I won't need to send this DDR3-1600 back now! :banana:
