THE Asus P5E X38 Thread

[cerealk1ll3r]

When you set the strap, go back down to the RAM frequency, and there should be different settings to choose from. For example, if your strap is 400 then when you go to set the ram frequency you might see different options, like DDR2-800, 975, 1066, etc. Different straps allow for different settings. 400 isn't necessarily the one you need.

so you're saying i should set the strap to 400?

I would suggest if you are running the ram 1:1 under 400 FSB and underclocked, to tighten the timings for better performance. I dont know if you will get CAS3 out of them, bet you might be able to get 4-3-3-7 timings. I was able to with my old G.Skill underclocked to 760.

As for the strap, these settings are the chipsets latency (similar to ram latency). The higher straps will loosen their latency to allow for a more stable overclock. But I've found with some of the straps, the board will not post. Hopefully this will be worked out with future bios revisions. I tested it before attempting to OC my FSB OC of 515. I kept the FSB at 450 and tried to run the ram at 1066 on the 200, 266 and 333 strap. I basically tried to run the ram higher first to see if it would handle 1066. It wouldnt post, so I ened up using the 400 strap and was 100% stable at 515 FSB with ram 1:1.

I'll get on it... My oc got all mest up when i swapped out my ram...

I need to get some DDR2 800 in my rig to get my save bios setting thing to load correctly... The ram i have in it now isn't cutting it... My board doesn't even post right most of the time... SUCK!!

I can post my bios config if anyone is interested...

Yes. please.

I got the next two days off i'll play with it some.

This is my Q6600 OC.

CPU Ratio 9
FSB Freq 400
Dram Freq 800
FSB Strap 400
Vcore 1.49375 (bios setting) Vdroop/Vdrop (1.384 load, 1.432 idle)
CPU ppl 1.62 (1.7 works too)
DramV 2.2
FSBV 1.34
nbV 1.37
sbV Auto
timing Auto

I have this going almost 7 hours too, but don't have a screen shot to show.
This board is an easy Oc'er. I also have the evga 680i mobo, which is very good, but not as easy oc'er as this x38 board.....but it is sli.

Anyway I like this board better. It's more stable and oc's without pulling jumpers, etc....just push start button and you're back in business.

You should be able to set your ram to 4-4-4-12 timings. I can run my Ballistix to 4-4-4-14 at DDR2 900 speeds!

Sorry for the 2x post, my wireless connection is slow tonight.

eric, I do run those tracers at their rated speeds/timings, but just not during my prime stability tests. Just learning how this mobo functions.. Will kick it up....

I also have the evga 680i mobo, soon to be the 780i upgrade.

I like this x38 board MUCH more than my 680i, as it OC's so easily.

Here's my P5E in action.

E6420 @450x8 = 3.6 24/7 on my P5E
