@serpentroyal & mrfatman
many thanks for the input..it's only kingston value ram 5-5-5-15 667 but as you say should be okay at 9x333..
will be checking everything thrice over anyway
Thanks, Roorooroo

serj,
Are you currently testing your rig in your sig for stability? If so, You need to up your vdimm to at least +.3V. Also, you might have to up your cpu voltage. This seems to be the norma. BUT every chip is different.

How's everybody else's score's?
3dmark 06 (3.2) (non OC) 9309
3dmark 06 (3.2 & 600/1000) 10655
3dmark 06 (3.6 & 620/1004) 11270
3dmark 06 (3.6. & 690/1090) 12094
That's a 2785 point spread
i need a new graphics card.I just went back to stock settings 2.66 but left the vdimm to +.3V. Speedfan now reports my Vcore2 (memory) to 2.26. That's up +.02 from a 3.6 overclock. LOL. I guess speedfan is not reporting vdimm correctly.
Any other apps I can use to see what my vdimm is in windows?

memtest ran with no problems for 3hrs and #5 test with 5 passes (followed ur instructions)
i just want to make sure whats the recommended voltage for the e6850 by intel, and what it needs to be to run 3.6ghz. i heard that i dont have to bump up the voltage when upping .6ghz on the e6850. whats the best way to check the core voltage? cpu-z im presuming?

Have you swapped forums?
Use Orthos for thrashing the cpu & Coretemp 0.95.4 beta for measuring temps.
sorry meant both ur instructions xD
edit: everest runs the stress test fine too, orthos is the one giving me problems.

I don't know if people can OC a 6850 to 3.6 without bumping the Vcore but I can't. On the other hand, I am a newbie and maybe it's possible to do so. I couldn't run a stable OC below 1.425V which gives me a Vdroop of 1.344 - 1.360 under full load.
On a side note, I have been browsing around the net about Core Temp and it's a known issue that it, for a matter of signed drivers, doesn't work with Vista 64. As far as I could understand, the only way to make it work under Vista 64 is to press F8 during booting and when the screen appears, uncheck or unselect the ''use signed drivers only '' . Once in Vista you need to run the program as an Admin. Anyways, I am not sure what kind of implications this could have on the long run if you do that and it's at you own risk obviously. If you want to try that, I suggest browsing around since I am describing the procedure out of the top of my head. I did try to use the procedure but, in my case nothing happen when I press F8. No Core Temp for me.
ohh i forgot about vdroop. i think mine goes up when stressed but i dont remember if it went to 1.3 i do remember seeing it at 1.2xxx but im guessing i have something enabled to play around with the voltage when idle...i will check it once i get home to be more precise.
also you have 4 sticks of ram, which usually makes it a little harder to OC, hopefully i can get away with 1.35v which i think was intel recommended vcore
EDIT: ok checked the voltage, idle my core voltage on CPU-Z is 1.040v and when i use everest system stability test its going up to 1.248v
my core speed is going 2400mhz idle and 3600mhz full load, im guessing my multiplier is fluctuating between 6x idle and 9x full load

yep i read previous posts and had missed it. I turned it off, bumped the voltage in bios and tested from 1.35 to 1.375, 1 level at a time, and it seems like i found the sweet spot. 1.375v in bios, shows up as 1.328 idle on CPU-Z and 1.296 load. i think thats within intel's recommended voltage for the e6850. Orthos has been running for 11hrs, will leave it for another hour or 2.
also how can i be sure what my ram voltage is. In bios i left it normal, but on easy tune 5, where u can overclock via OS, it shows 1.9v. im guessing the system is adjusting it so it would run stable? or is the normal voltage off, which is showing 1.9v
Thanks
btw mrfatboy, my rig looks similar to urs (with a few differences)

Hi, I have the DS3L version and a 6750.
Previously, I was testing to find the lowest Vcore at 3.4ghz and my last vcore was at 1.3375(1.296 after vdrop/1.28 under load). Well after returning everything to stock to benchmark so I could see my improvements, I moved back the settings I had before except I left Vcore to Normal (which is auto I believe). I loaded up windows and at load its running at 1.264v. Still running at the moment on Orthos for 8 hours with temps 41c and Cores at 48c-50c (cold night).
I was surprised at how low it was at load but I was wondering if it is a good idea to leave the vcore setting to Normal? Or should I set the Vcore at a specific voltage? After a simple calculation, I would have to set the Vcore to around 1.32v and after vdrop/vdroop it would be around 1.264. But at the moment there doesnt seem to be any problem with leaving Vcore to auto so i'm not sure since I read that leaving it on auto is generally not a good idea. I might push the chip more if I find the temps to be good during the afternoons.
Thanks.
EDIT
I just realized that I forgot to turn speedstep off so would that affect the Vcore at load?

i don't think so. Vcore will remain were you set it in the bios. EIST just changes CPU speed. Of course vdrop and vdroop.
C1E will reduce the vcore under low usage & I believe this works in conjunction with EIST. However, it wont affect the load voltage. vdrop & vdroop are features of all mobos, especially these Gigabytes. Mine is set as 1.45624v in the BIOS, in cpu-z it is 1.408v ilde & fluctuates between 1.392 & 1.376v under load. That's a whopping 0.08v difference between BIOS & load.
I don't think its a fault, just slack tolerances. You can do hardware mods to stabilise it but I dont think a BIOS update will do anything. You just need to compensate by over volting.
BTW, not been on the p1ss for 2 weekends running. Next weekend will change all that though.

actually C1E will use ur lowest multiplier (in my case 6x) times the FSB per multiplier u set (in my case 400mhz). so if i got C1E enabled, when idle, it uses 2.4ghz=6x400mhz. under stress C1E will bump it to 9x mutliplier making it 3.6ghz=9x400mhz.
The EIST on the other hand is the one thats supposed to lower the voltage when idle, but im guessing after a certain point it doesnt do much. mine stays 1.328 enabled and disabled. but when i had the vcore on normal before, it took it down to 1.00~1.27
Actually we're both wrong. Read this page on AT. C1E & EIST have quite distinct roles. C1E lowers the cpu voltage when a halt command is issued e.g sleep. EIST changes both multiplier and voltage when cpu demand changes. EIST usually requires BIOS settings to be at default for both voltage & multipier. Most if not all Core 2 cpus go down to x6 only & there are defined voltages for each multiplier.
Have these boards got huge Vdrop and Vdroop or is it CPU-Z not reading it correctly? is there any other software to measure Voltages accuratly?

Yes very sad news. Also the plane crash in Phuket. I was on that flight 6 months ago.
I suspect it's the boards' rather than cpu-z. You can use a multimeter if you know which points to bridge. I would leave well alone though. Do you really care?

I think im just bored tbh lol, ive got a Quad core and now after installing it and getting my temps down and overclocking it ive ran out of stuff to do and im bored again, although i have been playing War In Conflict demo and omg its amazing but the full games not out till the end of the month.
I know the feeling. I'm not allowed to play games just now though. We're stripping wallpaper & the wife's not impressed if I'm on the computer while she's stripping, fnarr fnarr.
I rearranged my case fans & added a 40mm fan to the NB HSF for something to do yesterday. The case fans used to blow from the side & now blow from the front which has helped lower the motherboard temp by 3C. The NB fan is mounted by screwing bolts between the fins which is a bodge but secure enough. If any drop out they'll land on the back of my gfx card & that'll be the end of that. I've got it connected via a 12v to 7v converter cable to keep the rotation noise down. I can now touch the HSF without burning my finger which is a good sign. There was no particular reason to add the fan as I dont intend to try for a higher overclock - just for longer term stability I guess. And for something to do
