TWIN2X2048-6400C4 + D975XBX2 overclock problem

Recommended Posts

I seem to be having issues with my TWIN2X2048-6400C4 in an overclocked E6700 & D975XBX2. Any time I get close to 3.3ghz, Orthos fails me. After a while I ran separate tests on Orthos for the cpu, and for the memory. The cpu had no issues but the memory alone would fail fairly fast on Orthos.

 

I have the ram set to 266/533 and also tried 266/667 (which takes the ram to 412mhz). It originally is set to default 5-5-5-18 1.84v but after reading the posts I tried manually setting it to 4-4-4-12 and increasing the voltage -- I don't have a setting for 2.1v but have tried the steps just below and just above, I believe 2.08v and 2.12v. I actually seem to fail sooner however at those settings. I am not sure if I should try any steps above 2.12v. Orthos will usually fail me on the memory test in anywhere from 1 to 5 minutes of testing. If I reduce the overclock to 3.2ghz (320FSB), it doesn't seem to happen (or else occurs much later).

 

Since I am reducing the memory to 266/533, shouldn't it be able to keep up with the increase in FSB for the cpu, since the memory is then running at something like 330mhz and the processor is passing its tests? I forget now what happens when I tried 333/667 but I think it was maybe the same. I left MCH/ICH/vfsb voltages alone, have the vcore at default + Enhanced Power Slope enabled. I tried briefly upping those a few steps but it didn't seem to help and made me nervous so I set them back again. I am not sure if those affect the memory stability.

 

Sorry if I am forgetting any information :) I am a noob at this. Not sure if my specs entered at registration appear with my post, so here they are again if not:

 

Core 2 Duo E6700

BFG GeForce 8800GTX

2GB CORSAIR XMS2 (TWIN2X2048-6400C4)

Intel "Bad Axe 2" D975XBX2 (bios 2333; newest bios versions unstable for me and 2333 was recommended)

PC Power & Cooling Silencer 750W

LIAN LI PC-V1000BPlus II case

WD Raptor 74GB 10K SATA150

WD CaviarSE16 320GB 7.2K SATA3

SAMSUNG dual layer 18X DVD±R w/LightScribe

Sony dvd drive

Sound Blaster X-Fi XtremeGamer Fatal1ty Professional

Sennheiser EH350 Headphones

Dell 30" 3007FPW @ 2560x1600

 

edit: right now I have a stock Intel cpu fan. Since it is the memory tests failing and not the cpu tests, I am not sure if that is the issue. Idle is in the 30s but can hit 70s under Orthos tests. I am looking at the ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler - Retail. I have always been klutzy at installing cpu fans and that one sounded easiest to install ^_^ and also did not seem to require removing the motherboard to install, which I don't want to do.

 

I am also not sure if stable household power is an issue, but was wondering if it is, and if so whether OPTI-UPS Enhanced Series ES1000C 1000VA 700W 8 Outlets UPS is a good match for my system.
