Not really sure what they'll do. 266x9 and manual timings is ok but my chip will do 3.6 so that's no good. Even 400x9 1:1 as others have said is a no no. I'm now running 425x8 which means i can run really low volts on the cpu and OC the mem a little, albeit with rubbish timings. Still good for a sub 15sec Super-Pi though.Quote:

Specs:
Antec P180 case with 4 Yate Loon D12SL fans (2 fans in push-pull on Scythe Ninja, 1 intake in front upper chamber, 1 intake in lower chamber)
Seasonic S12 HE+ 550 Watt PSU
P5W DH Deluxe 1.85 MCH version with 1506 bios (Thermal pads and covers removed from NB and SB heatsinks and replaced with AC5)
Intel C2E X6800 @ 3.20GHz (266 x 12)
2GB (2x1024) Mushkin XP2-8000 DDR2 RAM @ 800 MHz (2:3 divider 4-4-4-12)
HIS Radeon X1950 Pro
WD 500 GB SATA drive on SATA 3 channel
WD 160 GB SATA drive on SATA 4 channel
DVD-ROM on IDE channel master
BenQ DW1640 DVD +RW on IDE channel slave
The problems are:
1. System becomes unstable and spontaneously reboots (no BSOD) whenever 3D gaming or 2D video rendering occurs. The system is perfectly stable, and seems generally fine when idle, and even runs Orthos without fail. I was also able to transcode a 300MB Xvid to DVD format without any problems. Whenever I play a video or play a game, the system will tolerate a few minutes, then reboot without explanation (yes I’ve already unchecked “automatically reboot” in the advanced settings of My Computer).
I thought this was maybe due to my graphics card being faulty, so I swapped with another one and the same problem occurred. Core Temp and Everest reports the proc is running at around 41C at idle, and I’ve never seen it above 55C at load. Motherboard (SB) temp is reported at 39C in Everest. I’ve ruled out temps being the problem. I have latest Catalyst driver, but not latest MB BIOS due to the inability to adjust multiplier up on my X6800 with that bios. I’ve disabled HyperPath, DRAM throttling, Speedstep, etc in BIOS, but all voltages are at auto except for RAM which is at 2.2V. I figure it could be faulty MB or RAM at this point, but MemTest 86+ didn’t report any failures. I have updated the BIOS a few times, but never cleared the CMOS via jumpers, just used the /pbnc /n switches in AFUDOS. Any suggestions for how I can stop my system from spontaneous reboots?
2. Cannot seem to get stable even at 333 FSB, even with relaxed memory timings, let alone reach anywhere near 400 FSB for 1:1 memory operation. Not even trying to hit super aggressive clock on my X6800 (3.46GHz). This is not my main problem, just more of an annoyance as I’d prefer to run memory at 1:1. I can’t seem to hit the rated speed of 1000MHz on my Mushkin RAM and be stable, even at loose timings. I’m assuming this is due to dividers. Do I need to drop multi way down to 8 to run at high FSB?
Sidenine
Did you run RAM 1:1?
Did you check back in this thread on BIOS settings?
sparx
Sparx,
Yes, I tried running RAM at 1:1 on 266 FSB and same results. I basically ran everything at stock (including setting 266 x 11 for X6800) and had the same problem.
I've tried all recommended BIOS settings, and still cannot get a high stable FSB.
Wierd, as you said.Quote:

Also, you mentioned you did not clear cmos with jumper, it wouldn't hurt if you did. I know it sucks to have to reset all BIOS. :eek:
For a test, try running 3D03 and 3D05.

I have a drop off 0.02-0.03vQuote:

It doesnt seem to do this at stock settings so im wondering if maybe its a a bios setting i have wrong or if something is not getting enough (or to much even) power.
My temps are all fine cpu 40c idle 43c under load
and my mobo stays around 45-50c.
here is my machine and bios settings any help would be appreciated.
mobo-p5w dh (obviously)-1602 bios version
processor-e6600
gpu-evga 8800gtx
ram-crucial ballistix ddr1000 2gigs
cooling-vigor moonsoon heatsink
psu-ocz game X stream 700 watt
I know everything is put together right and its 100 percent stable at stock settings. With that said here ar my bios settings oc'd.
cpu frequency-378
dram-756 (1:1 ratio)
pci clock-33.33
memory voltage-2.2
cpu voltage-1.5
mch-1.55
fsb terminate-1.4
Also my Dram timings are set to manual and are at 5-5-5-15 with everything else in advanced chipset disabled except for Dram throttling. Advanced cpu has microde update and virtualization enabled and everything else is disabled.
I've spent alot of time researching overclocking online and your forum has the best and most consistently helpful support, Any help is greatly appreciated and i thank you in advance :toast:
Had similar problem and disabling Hyper Path 3 and Dram Write Recovery Time of 5 seem to fix it for me.Quote:

I have made some recommendations. However it is my opinion that running the ram at it's rated speed of PC8000 provides the most optimium performance. Therefore 333FSB maybe ideal for you if this OC does not work.Quote:

When we talked about Mushkin on page 2, we mentioned the fact that Mushkin warrants their memory up to 2.3V operation, while the other manufacturers all warrant 2.4V or 2.45V. It has been clear for a while now that Micron chips scale very well with additional voltage, so we decided to give the Mushkin some more juice to play with. And my oh my, have a look at the screen and the performance at 2.45V ! The redline has no trouble keeping up with the other memory kits now: it goes up to 1130Mhz, even surpassing the OCZ and Corsair performance… So if Mushkin had warranted…. You catch my drift.
Just happened again :( guess im gonna bump my fsb down to 333 and see what happens.
I had the exact freezing in games until I upped the mch to 1.65 V.Quote:

Just ran 3D05 and had 10,831 3dmarks. No errors and all tests ran without rebooting. Couldn't even run RAM at 1067 (1:2 ratio) with bump in voltage to 2.4V at relaxed timings, and my issue still doesn't improve by bumping DRAM Write Recovery Time to 5 at any speed (even my stable 800MHz). Bumped vCore to 1.4V with no stability improvement. Cleared CMOS by moving jumper, and no improvement. I just had another spontaneous reboot while installing a game and downloading some files at the same time. No heavy 3D or 2D rendering. Also forgot to mention that Firefox 2.0 will sometimes spontaneously close while I'm surfing (and doing nothing else). Is my mobo shot? Hopefully not, as the mods I've made (removing NB and SB covers and replacing thermal pads with AC5) has surely voided my warranty!
I'm re-running Memtest 86+ overnight to make sure no memory problems are detected, and will report in the morning.
1.65V is pure ownage :toast:Quote:

Edit: Also, what's better? 400 x 8 FSB, Or 355.5x9 FSB to reach 3.2GHZ?
When you removed the covers from the heat sinks did you retain them in one piece? If so just stick em' back on.Quote:

Like myself also.......but that's the risk we choose to take when modding...:rolleyes:
Something goes wrong......then your screwed........sorry.....but the truth.
Well not sure about that for all situations.
I rma'd one P5W dh Dx with the foil caps removed and replaced to Newegg with no problem. In my case the foil caps looked almost as good as new.
sparx
Memtest 86+ ran without errors again. Running Orthos now, but it's appearing to be stable (at least after 45 mins). Is the consensus that something is wrong with my mobo? Any other tips would be appreciated.
Me too I have been suffering for two days :toast:Quote:

Any recommendations before I start to put everything togther?? ofcourse I am here in this thread because the Momboard is P5W, I hope for no problems with that thing, you got me scared but hope for better result
Any recommendations, advice will be truly welcomed and appreciated
Here is my system:
Asus P5W
Scythe SCNJ-1100P CPU Cooling
Nexus 120 mm Quiet Case Fan
OCZ Gold XTC 1024MB PC6400 DDR2 800MHz
Microsoft WindowsXP-PRO SP2
XFX PVT71PUDD3 GeForce 7900GS 256MB 256-bit GDDR3 PCI Express x16
Intel Core 2 Duo E6400 Conroe 2.13GHz
COOLMAX CUG-700B ATX 12V( V.2.2) 700W Modular Power Supply
Seagate Barracuda 7200.10 ST3320620AS 320GB 7200 RPM 16MB Cache (SATA interface)
The only thing missing is the DVD/CD ROM it was out of stock
But I have now two old ATA IDE Hard drives, with windows ME installed, what do you think guys?
I want use at least one of them right now just to test the system if it is working or not:rehab:
Any DooS or DontS are VERY welcomed
:welcome:Quote:

So how do you recommend installing the IDE drive, is it tricky on this Mobo?
