@Praz ..those GSkills u used there are Powerchips?

Yes they are.

[ninjaskija]

Yes they are.

U have any mem settings that u can share at 500 FSB 1:1 for those? I still have problems stabilize them even after i pushed my NB voltage further...

I had no problem making 1000mhz+ with my OCZ PC2 8000 2X2GB sticks they ran 5.5.5.15.5.54 @ 2.0v with everything else on auto.

Have you tried using a divider other than 1:1 to see if you can get the RAM to run 1000mhz just in case its a 1:1 problem ?

I don't have the 8000's in my DFI P35 atm otherwise I'd check my self.

What program do u use for testing? I never get instability issues in prime blend(10h +) but it always failes in memtest for windows after 1h or so.

another thing... should i consider any specific mem settings for vista 64? or if is stable in xp should be stable in vista to..?

BIOS-reported voltages are:

CPU Core = 1.36v
DRAM = 2.08v
NB Core = 1.55
CPU VTT = 1.12v

I've disabled the Core Multi-Processing option as I believe this setting relates to hyper-threading and, to the best of my knowledge, this processor does not have this capability.

The key to stability with this Mushkin memory was setting tRFC to 52.

Performance level won't go below 8. I did try enabling Channel 1 Phase 0 Pull-In but the system wouldn't post, so I'm guessing I've reached the limit here.

The GTL settings were copied from someone else. As I have no real idea what these settings do and the system is stable, I'm happy to leave them at these values.

Memory benchmark:



The system is 18+ hours Prime stable although I have no screen shot.

Temps at 21C ambient as reported by CoreTemp are 39C idle and 53C load with large FFTs (assumes Tj max 105C).

As I reached my target overclock, I didn't try and push the system any further, although I may in the future.

another thing... should i consider any specific mem settings for vista 64? or if is stable in xp should be stable in vista to..?

For me what works in XP is also good for Vista 64Bit. I normally run Vista 32Bit first as it seems the most sensitive to stability issues.

U have any mem settings that u can share at 500 FSB 1:1 for those? I still have problems stabilize them even after i pushed my NB voltage further...

1:1 settings is what I'll post up as soon as I get the Crysis and UT3 benches done in XP, hopefully this evening. Here's a couple of BIOS screenshots till then.
