E7400 & Bluescreen

[ericmlaing]

Have an E7400(2.8) and have OC'd easily to 3.8 - have my FSB @ 400 RAM @ 1:1 I use the 400 and change the multiplier as I want to keep the RAM 1:1 when possible.
Here's the thing, 400 & 9.5x works great - P95 shows no errors, temps are okay etc etc... as soon as I go 400 & 10x I get a POST, system will boot, but just as Vista is loading it quickly flashes a bluescreen and the system reboots.
My vcore is generally on auto (but 1.37ish is usually what CPU-Z will show), RAM is @ 1.9v 5-5-5-18 with nothing else (voltage or clock wise changed), PCI is @ 100
I don't know what the bluescreen says as it's like a flash and gone kind of thing. I figured I made POST so everything should be fine - btw, Vista Home Premium 64 on a P5Q-E MB 4gb Corsair RAM
Thanks.

Have you tried raising the frontside bus and ram frequency? your ddr2-800 ram should be able to overclock a litlle bit since it's corsair. if it doesn't loosen the timing or increase voltage....

I know that this ain't the answer you wanted, unfortunately I don't know how to solve your multiplier prob...

By loosen timing, would that be like 6-6-6-18 kind of thing?

I brought the FSB up to 421 (just so I can see what happens with a 9.5x) and it brought my ram up a little bit... got farther into the vista boot but BSOD again... brought the ram voltage up a bit (2.0) got even farther but BSOD yet again. I'm wondering if I might just crap out at 3.8 😀

yes loosening the timing would be something like 6-6-6-18.... I have to admit that I don't have to much experience concerning ram overclocking so I think it would be good if someone else in this forum could help you.

What is the exact meaning of bsod(black/blue screen on???? or what?)

you said that when increasing the volts you got further so this tells me that now the ram are the problem and not the cpu, but it could also just be a random happening so that the real problem is still the cpu and messing with the ram is lost time....
