MonkeyyNinja Posted February 25, 2011 Posted February 25, 2011 First off, My specs; CPU: q9450 @ 3.00ghz RAM: 4gb DDR2 PC2-6400 Corsair Video Gard: GTX 570 SC Case: Antec 900 PSU: 850watt Antec Motherboard: P7N Diamond Since I built this rig, I have been running it at 3.0ghz with default voltages and timings. That setup has been all well and good until recently. I just bought an EVGA gtx 570 SC, and I wanted to make sure that my cpu would not bottleneck it. So I started tweaking things in the bios, trying to get up to the 3.2-3.6 range. Currently, I'm stuck with a slightly stable 3.3ghz clock, with my voltages/timings as follows: vCore: 1.3375 (vid = 1.2375) vNB: 1.350v vSB: 1.550v vRAM: 2.1v everything else on auto CAS: 6 TRCD: 6 TRP: 6 TRAS: 18 2T everything else on auto I say slightly stable because any time I try to play a game or open up a resource intensive program, I get memory related errors (but BSODs are rare, as are system crashes) after 5-10 minutes. Another thing I found interesting was that when running prime95 on "small FFT's", all cores run for hours without fail, while on "large FFT's" or "Blend", cores 3 and 4 always crash within a few seconds, but 1 and 2 continue running indefinitely. Any help I could get on getting this stable or even getting my ghz up further would be greatly appreciated (Especially since I actually got a performance DROP after upgrading from a gts 250 to my new 570).

IVIYTH0S Posted February 25, 2011 Posted February 25, 2011 I'll help you more when I'm home from school. for now run memtest86 on a bootable cd Share this post Link to post Share on other sites More sharing options...
Waco Posted February 25, 2011 Posted February 25, 2011 It sounds like your memory isn't stable at whatever speed you're running it. The easiest OC would probably be cranking your FSB to 400 MHz and setting the memory to a 1:1 ratio - that would give you 3.2 GHz and wouldn't be overclocking your RAM at all. If you want to go higher it would probably make sense to drop your CPU multiplier to 6x and see how high of an FSB your memory / mobo can handle (so you can narrow down what is failing at higher FSBs).

I was wondering if my memory was to blame. Thanks for the advice; I'll try it when I get home. Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted February 25, 2011 Posted February 25, 2011 Let us know if lowering the memory multiplier restabilizes you Share this post Link to post Share on other sites More sharing options...
MonkeyyNinja Posted February 25, 2011 Posted February 25, 2011 (edited) Let us know if lowering the memory multiplier restabilizes you Well, I tried running at 400x8, and got 5 minutes before the first core failed on prime95. Then I ran at 400x6 and got 17 minutes on prime 95. Both tests were on blend, and I didn't change any voltages. EDIT: all three cores from the second test that hadn't failed are still running as of this edit (about 30min).

IVIYTH0S Posted February 25, 2011 Posted February 25, 2011 what about the memory divider?? did you lower that or just the cpu divider?? Share this post Link to post Share on other sites More sharing options...
MonkeyyNinja Posted February 25, 2011 Posted February 25, 2011 I'm afraid I'm a bit too uneducated about this to know what your talking about. Sorry for my newbishness! Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted February 25, 2011 Posted February 25, 2011 can you post some pictures of your bios, i could tell you exactly what to change. (you may wanna read a Core 2 overclocking guide though if you don't even know this ) I'd be able to help you even better that way.

IVIYTH0S Posted February 26, 2011 Posted February 26, 2011 Why is your Core Voltage 0.10v, is that even possible Is "DRAM Clock" able to be dialed to any exact mhz or does it have a pop menu when you press enter onto it?? Share this post Link to post Share on other sites More sharing options...
Alexandre Posted February 26, 2011 Posted February 26, 2011 Why is your Core Voltage 0.10v, is that even possible Is "DRAM Clock" able to be dialed to any exact mhz or does it have a pop menu when you press enter onto it?? Maybe that 0.10v is how much it is above the stock voltage? Share this post Link to post Share on other sites More sharing options...
