What a nightmare, but thanks for the head's up. So basically to overcome this I would need to possibly choose the higher spec/priced 8000's in either the geil or corsair?
Will have to do a bit more reading up around the web.
Thanks again.

so avoid Geil as they do the same as crosair with SPD timings.
Just to clear things up will this board boot at 360+ FSB with Geil RAM at 400Mhz and timings set by SPD to 5-5-5-15?
If so would you be then able to tighten the timings using memset?
Sorry if this is a noob question:slapass: , I am just trying to straighten out all the information posted so far.
Thanks.
I have changed nothing in the subsystem. When I first started running this 6400HZ I ran it at 4-4-4-8 everywhere. I thought it was great to be able to run those timings at any fsb I could boot at. Then one morning I tried 3-4-4-8 and it booted just fine then it was 3-4-3-6,then it was 3-3-3-6 I now run this setting everywhere for the last few weeks and now this mem does not like 4-4-4.... at all anymore. Which is fine by me. I just thought it was a bit odd. when I go above 425 fsb I run my volts at 2.4 to run at any mem speed.
My board hits an absolute wall at 426,no matter what it will not boot there. Jump over 426 and it will boot up into the low 430's. I am happy with this but, Asus is hopefully not done yet with their updates there are still issues to be fixed here.. I run my mem on the turbo setting also if that helps anyone.
It is definetly a love hate relationship with these boards.

i sold the geil you have in your sig
Would have to do the maths. Have to explain I'm a bit of novice myself. I had mine on the P5W up to 900mhz(450*2) on a ratio (Can't remember the exact one) 5-5-5-15. As I say it did need 2.2v though for anything. Maybe my board was undervolting.Quote:

It would run 1:1 720mhz (360*2) 2.2v 4-4-4-12. Basically the memory would do pretty much what it should do, but not on a 1:1 ie. couldn't get fsb anyway near 400 anyway.
It's as nanoprobe32 explained.
By the way cheers again nanoprobe32. Would of been sick as a pig if I went out and bought those dominator 6400s. They're 200 pound here. Will try and get my hands on some HZ's.

Hi Nano
Damn I just bought this mobo but haven't used it yet. :(
So if I set the FSB to say 400MHz to get (266Mhz + 134Mhz) x 9 = 3.6Ghz with an E6600
(unknown Vcore - probably too high for 24/7 :D )
I would run my RAM at 4:5 i.e. (333Mhz + 134Mhz) x 2 = 934Mhz
with auto timings of 5-5-5-15 and with manual Vdimm of 2.1 volts?
Thanks.
As said you can't get your fsb that high(400), with the geil 6400s installed in the P5W board. I had a similar setup with my xeon 3060. The best oc for the cpu was about 3.2 ghz with this ram/mb combo. ie. :banana::banana::banana::banana:e.

Same everything - just a RAM swap.
I've got Geil 2.1V 4-4-4-12 RAM in my motherboard and it posted fine with 400 fsb bus using manual timings, however it wasn't stable running prime 95 on both cores though at this speed (but I blame the CPU).
Currently I'm running a stable clock at only 360 MHz 1:1 bus because of temperature concerns.
I lapped my E6600 but it didn't seem to help me at all.
Currently my room temp is nearly 30C (and rising, it's only 8am here :( ) and CoreTemp reports 53C on both cores at idle at this time while SpeedFan reports CPU=36C and System=44C.
The vCore is set to 1.37V and needs to be there to be prime 95 stable at this speed.
I've got a revision A E6600 processor though... So I'm guessing this is normal and there's nothing I can do about it.
Some details are:
Arctic Freezer 7 pro cooler with Arctic Silver 5 thermal paste.
ASUS P5W DH Deluxe MB with Arctic Silver 5 on northbridge and southbridge and stupid shiny covers removed from chipset heatsinks.
Crossfire setup with 2 x X1950XTX cards (serious heaters).
Antec P180B case, fans on low speed, extra 120mm fan hung on the back of the empty hard-drive cage in the top section of the case to direct air towards the graphics cards.
And I've been noticeing a good number of P5W owners trying the XMS6400 (C5) are having problems, While w/OCZ I haven't personally seen anything bad. :DQuote:

Guys...i have one question...
if i cant access to the Hardware monitor section in the bios...how the hell im i suposed to change qfan settings and stuff?
Thanx...
PS: This is really annoying...if i cant get it to work...im going to sell this POS board and wait for dfi's RD600 :(
EDIT: I was able to get into that menu using other ram sticks....weird huh? (Im using Gskill right now...but with some horrible generic sticks it got into that menu just fine)
Sorry for my english.
Well I have the xms6400 C5 and depending on which cpu I use different results..Quote:

Kind of I mean have not tried to go further yet, to busy doing other things I need comp to do..:toast:
Hello
I have read through the pages but i am a little confused to which is causing my system to become unstable cpu or ram? my PC is Stable 4hrs Orthos (stress cpu small fft's) but when i go blend i get about 5mins then the blue screen arrives. I have tried reducing the ram divider and upping the ram volts to 2.3 and the cpu temp is 58c full load (TAT) but still no joy! any help in getting blend stable is appreciated.
Firstly the machine

MCH Chipset voltage [1.85] i have removed the heat pipe and replaces with Thermaltake Extreme Spirit II Chipset Cooler
ich Chipset Voltage [1.2]
CPU Settings all disables except for Microdec uptadation and Virtualization Technology
CHipset settings timing by spd [enabled]
everything else disabled
Thanks in advance
I'm wondering just one thing about the P5 series with the 975X North bridge from Asus: would mounting the motherboard in a BTX style (upside down) hurt anything related to the chipset? I mean, the north bridge is cooled via passively with a heat pipe and fins but I remember reading about how--because of the heatpipe design--inverting them prevents proper cooling.
So, does anyone have good chipset temps on an inverted (BTX style) P5?
Ive Twin2x1024-6400C4, and i have some problems with fsb 400mhz(errors in memtest test 7), it only happens when rams are in dual channelQuote:

I'm using bios 1602. In windows xp pro the keyboard works fine.
Another problem is i dunno whether its related to the above problem, everytime i unplug the razer copperhead mice from the keyboard builtin usb hub, the next time i plug it back to the keyboard usb hub, the razer software won't be able to detect the mice again, i have to do a uninstall of the copperhead s/w then reinstall again then it will recognise it and be able to do mice configuration, i even plug direct to the motherboard back panel usb port but in vain ,i am using latest firmware/software for the copperhead and tarantula, wonder wat is causing this problem.

Hi JimB, I'm wondering what RAM you have exactly. I have this one: http://www.geilusa.com/proddetail.asp?linenumber=74Quote:

I've manage to overclock my cpu to 400fsb which gives me 3.6 GHz. What do I need to do to overclock my RAM? What settings should I use to get 1:1 or 4:5?
Spec in sig. Thanks!
1:1 would be the DDR2-800MHZ setting
4:5 would be the DDR2-1000MHZ setting
:)
Would my memory need extra voltage to run at 800MHz? I'm assuming that because its DDR2-800, it's designed to run at 800MHz? I'm new to this so I may be completely off!
look at the ram packaging and see what voltage it's rated to run at
RAM packaging?? lol, thats long gone! I'll check the OCZ website to see if I can find anything. Thanks.
