P45T extreme - easy 600FSB settings?

[Jimba]

Hey,

 

So I'm trying to see if my p45t extreme can do 600FSB.

 

So far I been able to do 520FSBx6 32M but can't get higher without it freezing.

 

On air cooling.

 

I'm trying to just try it to see if it is possible with my E8600.

 

Also does anyone have any good settings for 4ghz with high FSB?

 

Using cellshock C8 1800 black D9GTR.

 

Thanks,

Hi, I was overclocking my EP45 - UD3R recently. I have very good E8400, did ~660 MHz FSB on P5E3 Premium and ~640 on Rampage Formula X48. I know these motherboards good.

Using the same processor on UD3R I noticed, that 600 FSB is possible only on "auto" settings. I will make a small thread about overclicking on this platform.

I can say that when P5E3 did Stable 600 FSB on:

vCore 1.3 V

vTT 1.2 V

vNB 1.413 V

vPLL 1.526

SKEW CPU +400

SKEW NB +100

tWR 10

tRTP 5

 

Gigabyte EP45-UD3R wasn't able to work using these settings... but if AUTO, it works, BUT IT SETS EXTREMELY DANGEROUS VOLTAGES!

 

EG.

All Auto, ram 1:1, timings 5-5-5-15, booting on 500 MHz and it sets:

vCore 1.35

vNB 1.4

vPLL 1.85 V ! ! !

vTT 1.6 V ! ! !

vMEM 2.0 V

 

I was doing it on AIR and my heart was beating ten times faster because of this stupid motherboard. I never set above 1.45 VTT, it's extremely dangerous.

 

I have lots of screenshots, will put these data to math sheet and find proporties and ratios or something.

You gotta be kidding man (with not reaching 660+ already). Best ram for 775+ddr3, best (but not easiest) board for very high fsb's.

 

I had an EP45T-Extreme lent to me. 650FSB was easily achieveable with only 1.26V VTT. You should not leave many options on auto in bios.

PLL is good on stock, or many times, even under stock 1.50V, but let's stick to stock for now.

VTT: 1.26V

MCH: it depends on your ram settings, but from 1.20 to 1.50 will work.

SB voltages are good at stock, even for 700FSB

The most important 2 things to take take care of are:

1. It has no llc and drops a LOT, so give it voltages accordingly

2. You have to play with MCH Ref and MCH/DRAM Ref settings much more than you have to with voltages.

 

Oh, 1 last thing: you didn't write what cpu you're using. A Wolf' 6M is needed for "easy" 600+, I hope you know that.

Thanks for the info! It is very helpful!

 

The CPU I am using is a E8600 that can do 610FSB on a REX.

 

As for ram I do have a kit of hypers, would they be better then D9GTR/D9JNL?

Both will work
