OC Problems

[fmc_boss]

keep on increasing the vcore by 0.25 volts until u get stabilty,but check ur temps.

 

Don't you think that's a little high??

 

This isn't the first time you've been pulled up on this.

icry,

 

try these settings. some are a little aggressive but once you get stability you can start backing down on the voltages and tightening some things up.

I recommend trying the B-straps first. If that doesn't work then you can try the D-straps. Notice that when you change your straps/memory multipliers that your resulting RAM speed changes also. So keep that in mind.

 

If you can't boot at a 475 FSB, then leave everything else alone and reduce your FSB in increments of 5 until you get a boot and stability - we can work from there.

Thanks, I will try when this out when I get home.

how long should prime run without issue before your in the clear?

 

I let Prime95 run overnight (8-9 hours)

When I wake up in the morning it's kind of like Christmas day finding out whether or not your o/c passed the test

Seriously though - if your machine passes 8 hours of memtest, 8 hours of Prime and some 3DMark video stressing then you should be solid as a rock (toaster stable we used to call it in the day........)

[wevsspot]

Other than the four primary memory timings - the ones that will have the most impact on your stability are;

 

Performance Enhance = Standard

 

Refresh to Act Delay = 60 or higher

 

Static tRead Value = 7 or 8 (this is "performance level") very important you start at 8 to loosen things up a bit or it will never run right

 

I've got your voltages a little high to start with, but no where near the danger zone. Once you get stable you can always start backing them off a little at a time.

 

I think your ram should run fine at 8-8-8-21 or 8-8-8-21 primary timings. If not, we may have to loosen those up a bit too. Keep me posted.

That's a lot higher than I would suggest for that OC, but if he can get it stable and quickly start lowering the voltages he should be OK. I know he will be very grateful if these setting are stable on his system and give him somewhere to work from.

 

The only thing I would suggest is to let him try to get stable at the rated timings before trying to tighten the timings. Either way I hope it works out for him.

Okay, I have everything in as you have here. I put the ddr3 overvolt to .35v, mch to .30v

CPU GTLREF2 VOLTAGE NORMAL.....these 2 settings are not there

 

Everything else is exactly what you said. I am booted into windows right now. It didn't hiccup at all saving out of the bios. started running prime and it bluescreened. what should i adjust first?

[CowKing]

you need to take that PCI Express Frequency and set it to manual at 100MHz (this won't make it stable, but it'll help not kill you video card)

Definitely don't want that. Changed.

[joel.monteiro]

have u tried a smaller oc like 3.2-3.4 ?

[RJR]

FSB: 420

Memory Multi: 3.33D

Std Timings: 9-9-9-24

Adv Timings: Auto

Vcore: 1.35v

 

everything else where you have them, run Prime "SMALL FFT" for 15 minutes, if it passes then run "Blend"

[wevsspot]

I couldn't ever get the "D" straps to work very well for me (but I was using G.Skill memory).

 

Anyhow, I concur on manually setting PCIe Frequency to 100 - although I've never seen a BIOS auto adjust it to anything other than that.

 

Right now I'd leave everything exactly as you have it EXCEPT for moving FSB down to 450 and CPU core voltage down to 1.3500v and give it a go from there.
