I7 860 gbt ud4 trident help overclock!

davidexD · 10-28-2009, 04:24 AM

i don't know if this is the right place to write this kind of thread. and this is the first time that i try to pump a nehalem configuration.

i need to reach 4 ghz on this configuration and i don't know where to fix on this bios

What CPU cooling you on?

Realistically you will need the vCore at around 1.32v. 190x21 you might be able to keep the VTT and PLL at stock. RAM multi at.... x4? (giving you just under 800MHz on the RAM...) start low on the RAM and work up when you have a base to work from. Timings at 800MHz... 7-8-7 should be alright

.......and welcome to XS!

thanks for the welcome, liquid cooling for the cpu the best italian waterblock, the trident ram are awesome reachs all kind of frequenchy so in not worried about.

i tried with just 1,32 1,34 1,40 ,145 but it doesn't want works. blue screen on the win 7 logo again and again.

Ah... just thought of something. I did 4GHz with Turbo disabled. If I enabled it, things stopped playing nice as part of the CPU is trying to run 4.4GHz or so. If you have Turbo enabled, try disabling that and E1ST. Your whole chip will still be running at 4GHz... plenty of power

davidexD · 10-28-2009, 08:19 AM

i've already disablead e1st and all the cstate and turbo too. thanks anyway.

DDR3 memory run at 1600MHz should be multi x8.

Depends on BIOS. MSI cuts it in 2 to give "actual" MHz

Thats weird... if you've tried way higher voltages and it still wont even load Windows. Hmmm. Try VTT to 1.3-1.35v?

davidexD · 10-28-2009, 08:45 AM

but how can i get on vtt max? in a safe way.

K404 · 10-28-2009, 09:07 AM

1.30v should be totally fine

davidexD · 10-28-2009, 12:59 PM

it works thanks very much!!

K404 · 10-28-2009, 01:14 PM

So it was VTT holding you back?

Glad you have some MHz now, lets see some screenies!

davidexD · 10-28-2009, 01:24 PM

and if i want for example reach 4,4 i must give much more vcore and much more vtt right? like 1,45 vcore and 1,40 or 1,45 vtt?

davidexD · 10-28-2009, 01:44 PM

yes i reached 4 ghz but it's a bit hard to pass linx for only 1,3440 of vcore, i'm very newbie on this kind of sockets

K404 · 10-28-2009, 02:00 PM

4.4GHz stable might be dangerous to aim for. Both for chips temps and for the current draw through the socket 1156 isnt strong enough, theres a big thread in the Extreme overclocking section. Frozen chips at 4.9-5.1GHz (the ones suffering problems) are drawing ~ similar current to watercooled chips at 4.1-4.2GHz.

davidexD · 10-28-2009, 02:02 PM

i saw in a italian forum that a guy with my same configuration keeps 4 ghz with only 1,3440 where i can fix for save some volts? this bios for me is a total chaos!

K404 · 10-28-2009, 02:14 PM

Im using an MSI board, sorry I cant help you there

davidexD · 10-28-2009, 02:16 PM

ok but thanks again for the vtt, i was going crazy for it!

davidexD · 10-29-2009, 05:41 AM

can somebody help me for save some vcore on gigabyte board??

hokiealumnus · 10-29-2009, 05:52 AM

That's actually very good Vcore for a stable 4GHz. My chip takes 1.37v loaded to stabilize at 4GHz...and that's without HT. As mentioned before, 4.4GHz is going to be very difficult to reach and if you do get there, it will not be with much stability. Even the best of these chips don't really do that for 24/7 clocks. Here is a thread showing some 860/870 overclocks for you to reference.

davidexD · 10-29-2009, 05:58 AM

no i'm not stable with 1,3440 at all, i'm searching a right voltage but i think it's very tall.i need to tweak the bios but i don't know anything about gigabyte bios.

RJR · 10-29-2009, 06:15 AM

What is your LOAD vcore?
Do you have LLC enabled?
Gigabyte P55 boards have a steep vdroop (at least mine does).

davidexD · 10-29-2009, 06:47 AM

what is llc? i set in the bios 1,34 but in load it jumps to 1,368 so strange

stasio · 10-29-2009, 07:00 AM

For start read this review for UD6 and implement on yours UD4:

davidexD · 10-29-2009, 07:03 AM

nice guide but is not the same mobo for example i can't choose the level of the loadline calibration.
