so we never did hear back from EVGA about the voltage concerns/questions that were raised earlier in this thread...

Hello friends. I'm having trouble on my i5 on p55 ftw. I can not overclock stability. I'm currently trying:
Clock = 3.7 - 195x19

BIOS
Vcore = 1.28v
VTT = 1.22
PCH = 1.05
PLL = 1.80
VDIMM = 1.65

I think my problem is the VTT, but according to intel site, it is advisable to pass the 1.21v. What is the recommendation and that voltage would be nice to use the 3.7/3.8 GHz vtt? Thank you for your attention, sorry my english

My views on VTT

I thought I'd post these here since I just finished typing them up elsewhere.

Here are my settings for a nice stable 3.8Ghz/200BLCK.  I get a consistent 52GFlops in Linx 8-thread using all memory.  Hope this can help someone.

vcore: 1.281v (Bios) 1.305v (E-leet) 1.33v (load E-leet)
Vdroop disabled
VTT: 1.375v (bios) 1.375v (E-leet) 1.38v (load E-Leet)
Ram voltage: 1.64v
PCH: 1.05v
PLL: 1.8v

CPU multiplier is 19x
BLCK: 200Mhz
PCI-E: 104Mhz (But I don't notice this making a difference)
QPI: 4.8GT/s

CPU PWM Frequency: 1189KHz
VTT PWM Frequency: 634KHz
DDR PWM Frequency: 634KHz
CPU Signal 1: Less
CPU Signal 3: -31
CPU Signal 4: -31
CPU PCIE 1/2: Auto
DDR Signal 1/2/3: Auto
DMI Signal: -31
PCH Signal -31

Ram settings are: 1333Mhz (2:10) for 2000Mhz 8-9-8-24 (rated values)

HT is disabled.  Gaming and LinX actually perform better without it due to the way it is implemented by Intel.  Also, helps to reduce CPU temperature output.

Power saving features are disabled. :(

Anything unmentioned is on Auto/default.

I have the H50, and my only experience is that at full load in prime 95 at stock settings my CPU is only at 40C.  I would guess that leaves me a bit of headroom for overclocking at a later time. 

Cookies08 Hey guys!

a complete noob @ overclocking here :( was just wondering if you could give any advice on my first time overclock i have

EVGA P55-FTW Motherboard
i7 860 CPU + Standard Heatsink/Fan
OCZ Gold Low Voltage 2 x 2 GB DDR3-1333 PC3-10666
 
Is this overclockable as it stands or do i need to purchase a new cooler?
im running a ****e GPU (ATI Radeon X2600 :( )

Gretaful for any Advice received as i love this board its awesome !!

Also anyone have a spare EVGA grafix card GTX prefered :)

You may be able to get a small overclock on the stock cooler, but don't expect too much. Having DDR3-1333 RAM is going to be a potential limiting factor as well. Don't be afraid to try though, just keep a close eye on the temperatures.

where do i start would that guide work for me or would i be better off buying a new cooler and ram?

hey guys quick question which is the better ram here i have 3 sets

Kingston 3 GB DDR3 SDRAM (KHX16000D3K3/3GX) DDR3- 2000MHz Kingston 3 GB DDR3 SDRAM (KHX16000D3K3/3GX) DDR3- 2000MHz Kingston 3 GB DDR3 SDRAM (KHX16000D3K3/3GX) DDR3- 2000MHz Kingston 3 GB DDR3 SDRAM (KHX16000D3K3/3GX) DDR3- 2000MHz Kingston 3 GB DDR3 SDRAM (KHX16000D3K3/3GX) DDR3- 2000MHz Kingston 3 GB DDR3 SDRAM (KHX16000D3K3/3GX) DDR3- 2000MHz
Kingston's KHX16000D3K3/3GX  DDR3-2000Mhz 3gig Kingston 3 GB DDR3 SDRAM (KHX16000D3K3/3GX) DDR3- 2000MHz
the ocz thats in it at preseen

or

4GB G.Skill DDR3 PC3-12800 1600MHz HZ Series (7-7-7-18) Dual Channel kit

basically is the kingston ram worth buying in @ €80 will it perform better than the ram i have ?

i get the watchdog time out only when I disable memory remap its odd

You're not going to get 6GB for sure, because the P55 has 2 memory channels, so really your options are 2, 4, & 8GB.  If you're only going to run 32bit, then if you get 4GB, the system won't be able to use it all.  Personally I'd recommend any new system run the 64bit version.  The only reason I could see for not doing that is if you had a device who's driver specifically doesn't work in 64bit, and that should be getting rare.  When I was doing 64bit vista, a few of my devices like the iphone and an e-reader didn't have 64bit drivers at first, but even then that eventually got sorted out.  So I'd recommend running Win7 64bit and I'd say 4GB should be fine.  I have 8GB in my current system, and I think it's a little overkill for me.  If you're doing some real audio/video work, then I could see going 8GB.

I have an Classified 200, a Core i7 860 at stock, Patriot G Series ‘Sector 5’ Edition 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666), and a Arctic Cooling Freezer Pro 7 Rev2 and a 9800 GTX+ at 800 MHz. I was wondering if I could take baby steps and just get it to 3.5 GHz(166 Freq), since I am running lower frequency RAM, and don't want to toast my board. The AC Freezer Pro 7 came with already applied MX-2, even though I already have everything put together should I remove the MX-2 and apply Arctic Silver 5?

I only changed RAM settings once on a LGA 775 board, but I still have yet to get comfortable

Could you please guide me, since I tried your method with a 166 CPU frequency, and tried to run the same frequencys in your method for RAM, but it didn't work well.

Thanks
Regards
Ken

Is the multiplier locked @ 21 on the e657? I haven't been able to change it??? Also is it best to run a higher multiplier or a higher BLCK? I can't go past 160mhz with Jacobs OC advise  

sirmille__try posting below in the normal section, you should be able to get a lot of help. Also, take individual screenshots of E-LEET so people can read your results. Run LinX at max memory and post those results too. Also, what cooler are you using_

In FF if you right click on the pic and 'view image' they'll get bigger so you can see them but I'll just make 'em bigger anyways next time. I'm using the Cooler Master V-8 in a Antec 1200 case.

Hi guys, i got a P55 mb and try to overclock my core i7 860 @ 4.2Ghz following this guide.
Even if i set Vcore to 1.425 it's not stable on prime95/OCCT. Something I forgot ? SpeedStep/HT/C-State/C1E Disabled. I've the huge NH-D14 so temps are under 80° at 1.425V.

My ram G.Skill DDR3-1600 set to 7-7-7-24 T1 works fine. Do I need the 2nd 8pin connector ? But i don't think so (TDP is 95W). Also which Bios are you using (mine is A59) ?

Here are the E-LEET screens
