Aye, I've got 4x1 gig sticks of GEiL DDR2-800 RAM, and it won't run at 800 mhz at all :( I've got a 400mhz FSB with my E8400 and I really want to run the RAM at its rated speed at 1:1 ratio :(
I was told earlier on in the thread that 975X has problems with 4 RAM slots being filled.
Using SPD timing doesn't help, nor does increasing the volts :(
Yes, it's very difficult to run 4 sticks of memory at stock speeds. Not only 975X has such problems. Same problems happen with 650i or 680i with 4 memory slots filled.
Dunno. Mine ran fine with 4x1 sticks up to rated 1066 although it is possible that they prevented me from achieving FSB over 400
hi all
I have problems when trying to run 4 sticks of ram on the p5w. System is:
(p5w) - BIOS 2704
Intel e6600 stock with thermalright 120 ultra extreme
2x1G Corsair 6400C4
2x1G Crucial Balistix Tracer 6400
4x750 + 1x640 HDDs with various raid volumes
Digitalnow quattro s-t tv capture card
Creative Audigy 2 zs platinum
Coolermaster Real power 850W psu
Symptoms vary, but usually what happens is:
0. (computer is off - has been off for at least 15 minutes)
1. Turn on computer
2. Video card posts
3. You hear a single beep indicating normal post
3. Mobo hangs on post (you see the p5w splash graphic, but nothing happens - have waited for hours)
Other symptoms i have had include:
- no post at all - this only seems to happen when the crucial sticks are in the orange slots and the corsair sticks are in the black slots
Eventually i can make the mobo post and load the OS etc by LEAVING the computer frozen in post for at least 10 min (if I only leave it a short time, it doesn't tend to work) and then powering off and powering back on (reset doesn't seem to work at all). When the mobo does eventually post, it sometimes tells me that "overclocking has failed" and I have to go into the bios (changing nothing doesn't stop the OS loading next time), but at other times it just loads the operating system straight away. This procedure doesn't always work (ie. the computer won't always get to the OS on the second attempt), but eventually after enough powering off and powering on it will 'randomly' work.
The interesting thing is that once I have got into the OS, I can shut down the computer and it will always work first time if I try turning on the computer again after no more that 1 or 2 minutes. It is almost like the RAM needs to warm up!
How do I know this is caused by the RAM? I am not 100% certain, but here are a few points and questions:
1. If I use less than 4 sticks, the computer will always work first time.
2. I can get rid of the splash screen, and when I do this i see that the last thing shown in the printout is something about usb device detection. The next thing that should come up is the ram detection stage.
3. I usually run my ram at 2.2V 800mhz 4-4-4-12-4 - I am currently trying to run slower speeds and looser timings, but this doesn't seem to help. I haven't tried "default to spd".
4. I wonder whether the bios battery could be dying
5. I wonder whether this could be caused by a hardware incompatibility. I haven't actually gone to the length of pulling out all my expansion cards and trying to post with 1 hdd, vid card, and the 4 sticks of ram, but at various times I have had each of the cards out individually with no change.
6. PSU should be more than adequate - to ensure this i pulled out all power except mobo and still had issues.
7. bios memory setting?
8. could be a memory seating issue, except that i have had the sticks in and out often and whenever it is only 2 or 3 sticks it always works
9. dodgy memory stick - when the mobo gets through post I've been able to run memtest through and I get no errors at all.
10. the cpu and vid card are *NOT overclocked*
So in summary I'm looking for advice from people who might have come across similar issues to what i am encountering. I keep hearing of people who are able to run 4 sticks in this board without any issues so i wonder whether it is something that I'm doing wrong. Any advice or constructive comments would be appreciated.

Well first thing to do, I think, would be to put two sticks in, run memtest (built into Vista if you have it) and see if it reports any errors. Then put in the other two and run it.
Hi Radlord
Thanks for your comment. As I said in my first post, memtest runs and finds no errors with all four sticks in at 800MHz 4-4-4-12-4 - obviously I can only run memtest on four sticks after it has got through post though. I have also tested the sticks individually at this setting (and higher) and they check out fine.
Since I posted last I have tried setting bios to use spd, as well as trying manual settings at 533MHz 6-6-6-18-6 - neither of these settings worked...
hmmmm. How weird.
Maybe try bumping the volts up on the Northbridge a wee bit?
New Core2 E7400 is released with very high 10.5 ratio and on new R0 stepping, making it possible to get 4.2GHz at only 400FSB.
I wonder how that R0 stepping overclocks :). I think it should be much better than M0, just it was in case of E0 compared to C0.
Well people, after change my PSU to a new Corsair TX750W, i can reach the 380FSB easy, as you can see:

It's a weird, but with my old PSU (thermaltake pure power 680w) i not pass orthos for more than 1H.
Seems that the PSU is a very important thing to oc sucess.
So, for now, 3.6ghz in cpu with 2.1V in 4 x 1GB DDR2 is not so bad. :D
CPU Frequency: 380MHz
DRAM Frequency: 760MHz
Performance Mode: Auto
PCI Express Frequency: 100MHz
PCI Clock Synchronization Mode: 33.33MHz
Memory Voltage: 2.1V (if have 2x1GB, only 1.8V)
CPU VCore Voltage: Auto
FSB Termination Voltage: 1.3V
MCH Chipset Voltage: 1.65V
ICH Chipset Voltage: 1.05V
SPD - Enable (timmings - 5-6-6-18)
Good and old motherboard :clap::clap:
this mobo served me well, glad to see it's still going strong : ) *salutes*
designed for 2 stick dual channel, 4 stick imagine is unstable? :/
I'm still using Bios 2004.
Using it overclocked now for over a year. It is stable. Do you guys recommend upgrading or will there be no difference noticable. "If it ain't broken.... " ??
The reason i'm thinking about upgrading is that i'm seeing "only" 2gb in stead of 3.2gb in Vista 32bit. Do you think it is because i have a 640mb videocard ?
Using it with
E6600
4x1gb HyperX mem.
8800GTS 640MB
That's exactly what I am running but in vista 32, stable as well. However I am much hotter....idle 45 C, load 57 C what cooling are you using? Should I be worried at my temps?Quote:

EDIT: Paul your temps i think is fine. I have the cpu in 26º at IDLE, and 38º-40º FULL
So, after 3:30H of orthos, i run one 3dmark06 test with my 380FSB and my new Corsair 750W.
Test are fine and after finish the test i played in GRID game.
Well, first racing, in the second lap , have a BSDO (machine_check_exception)....
Seems , that 380FSB with 4 x 1GB, is to forget with this board... Or should i put some vcore voltage in cpu?
I still have the problem in vcore cpu - bios allow me in 1.45v - 7V. Less than 1.45v i cannot define.
So, back another time to 370FSB with my 4 x 1GB. - STABLE LIKE A ROCK AGAIN.
In the future i will change my memories, and put some 2 x 2GB DDR2 800 KIT.
For now, i still have a little happy with this OC.
Finally got an E8600 to replace the E6600 but without changing the good old P5W DH, here is the result:

My easiest overclock ever! Thanks to all that helped me before getting the 400 fsb bootable and stable :)
Nice oc firestarter.pt,Quote:

If you fix the core voltage, what P5W DH revision you have and bios version?
In mine revision (1.02g) the minimum that i can select is 1.45v
My board revision is the same as yours and I also can not set the voltage bellow 1.45v but it's no problem because it's a very good value for a moderate overclock.
Surprising with this CPU for the first time ever I'm able to boot this motherboard above 400 mhz fsb, I'm benchig at 10x 420 = 4.2 Ghz at the moment and it looks stable but I still have to test it with Orthos and after I'll try even more but I'm more than happy with 420 :D I never expect to go beyond 400...
Hello i'm from Portugal and like u all a proud owner of an p5w. Although i think it's a good board i'm havin' problems with my OC. here is my rig:
Q9450
Corsair 2GbX2 (1066Mhz)
HD3870X2
P5W DH Deluxe (bios 2704)
Asus Silent Knight II cooler
I've tried to set FSB to 385Mhz and the mem to 976Mhz, everything ran smooth, crysis ran better than ever but it always kept crashin' (BSOD). I don't know a lot about voltages but everytime i changed them i had too clear cmos.
Can someone help me?
Daimao, our board isn't the best overclocker with quad-core CPUs. However, you can try increasing FSB Termination Voltage, MCH Voltage, Memory Voltage and CPU Voltage. Post a shot from your current settings and it will be easier for us to help you.Quote:

Try turning on Memory remap feature in BIOS (or turn it off if it is on). The videocard does not have anything to do with this.Quote:

For example my cpu/system is stable at 420 FSB with 2 x 1gb
But with
2 x 2gb i can only run stable at 400 FSB
(no matter mch etc. voltage i use)
I tried to change the mem voltage to 1.95. Its more stable but i still get the BSOD.
I'm having with my memory too: it only recognizes 2.6Gb.Quote:

Update on my E8600 - Now 4100 Mhz rock solid!

BTW, from what I read ppl use very low memory voltages, is there a reason for that? I use 2.25v since 2 and half years with no problems and good results (considering the 5-6-6 timmings limited by this board).
Very good results.Quote:
