Problems with multieplier, FSB, and vcore

post #1 of 12
Thread Starter 
i have a conroe X6800, asus P5WDG2 WS Pro (latest bios), corsair XMS2 4gb (4X1gb) DDR2 1066 (PC2 8500) water cooled.
current settings:
core speed: 3854.5
multiplier: 11
bus speed: 350.5
rated FSB: 1401.7
vcore: 1.4675v
ram freq: 525.6
FSBRAM 2:3
ram timming: 5-5-5-15

i've also been able to use the following configuration.
core speed: 3650
multiplier: 10
Bus speed: 365
rated FSB: 1461
vcore: 1.4875v
ram freq: 548
FSBRAM 2:3
ram timming 5-5-5-15
mem voltage :2.35v

other settings: pci-e freq:100 pci clock 33.33mhz hyper path 3 disabled, dram ecc mode disabled, dram throttling threshold disabled, micro code updation enabled, max cpuid value limit diabled, execute diable function disabled, single logical processor mode disabled, enhanced c1 control disabled, virtualization tech diabled.


this is the problem, when i try using other multipliers it underclocks my cpu.
what am i doing wrong. I.E., multiplier 9X cpu freq 400=3600 it doesn't work.

I would suggest dropping your clock speed back down to stock when changing the multiplier and working your way back up to the CPU's maximum speed. Not all boards do well with very high FSBs, so it's possible that going up to the 400x9 example you used is pushing the system beyond what it can handle. Alternately, you may need to tweak other voltages in your BIOS such as the MCH voltage. Going from stock 266 to 400 is a pretty far way without tweaking numerous settings.

It sounds like you're very much on the right path with the higher multipliers. Just apply the same overclocking techniques to the lower ones and add in the extra voltage settings.

you may need better cooling to hit the higher fsb on your northbridge. I'm not familiar with the NB cooling on the P5WDG2 WS Pro, but if its anything like the rest of the P5 line it has only a mediocre heatsink. If anything try reseating the NB heatsink with some AS5.
Also, if you are going to change your multiplier, do it from stock and slowly increase your fsb. don't be hasty.

thanks guys. i've started from the beginning again and it seems to work. as i write this i'm using a multiplier of 9 and a FSB 325=2926. i'm using a Swiftech MCW30 Chipset Cooling Water-block to cool my northbridge and southbridge. i've got everything underwater. i want to upload a picture so you guys can see. let me know how to do this. thanks again. i'm going to continue with lower multipliers to see how far i can get the FSB.

For pictures, you can click on the "Go Advanced" button below the posting window, scroll down, and click on "Manage Attachments" to upload a pic. Alternately, you can use a free image hosting site such as our own www.rigshowcase.com or our site's image gallery (see link at top of every page on the site) to host your photos for you and then link them in your posts.

Good luck with balancing FSB and multiplier. I hope to have time to do the same on my system soon.

kicking butt and taking names. thanks taeric, i've been able to really push my rig. here are the new stats
core speed: 4014
multiplier: 9
bus speed: 446
rated fsb: 1784
mem freq: 446
FSBRAM: 1:1
timing: 4-4-4-8

at first i hit a wall @ bus speed: 367 and i couldn't figure why. then i put the dram freq in the bios to auto and i was able to push through. there was a trade off though, being that the corsair memory is rated at pc2 8500 i had to downclock it to pc2 4500 in auto. finally i was able to get it up to where it is pc2 7100. is a 1:1 ratio on the ram to dram good. let me know what you think.
