I use 1.40mch for my 24/7 at 500*9/1250 and when I had the stock heatsink on it would get pretty hot when priming even with a fan on it. I also noticed that since the first ram stick is so damn close to the nb heatsink it would get alot warmer than the second stick. I ended up getting an EK 5 waterblock for the NB which took out alot of heat and keeps it away from the ram which stay at even temps now. If I were you I would atleast pull the blue cover plate off the nb and put a fan on the heatsink and ram.

LOL, seriously u havent said anything remotely beneficial, other then how ur hand feels. Im hoping someone has some crediable data. No offense Hoss

You indicate your nb is hot to the touch, you get two very good tips and, you haven't bothered to even try them out and you still want more? And the rudeness....

FWIW Hoss' tip is excellent. How do I know? It's what I've done; pulled the top cover plate and have a 40mm sitting right on the nb, and my results are close to what these guys on water have.

Overclocking is all about being creative, and the little things actually make a hell of a difference. With your attitude, no one will help you; which is not bad because sometimes learning things the hard way has its own rewards.

For those on strictly air trying to run with the big boys, you definitely need to use better thermal paste, be sure your mobo is not warped and that the mosfets are making good contact with the heatsink, peel of the cover plate on the NB (may void warranty, shouldn't ), then put a fan on it, preferably one that blows towards the mosfets too - if your cpu fan isn't the type that blows cool air to surrounding components.

Here is a quick run I did just did to show that 1.7v on the nb is possible with active cooling on the nb.

1.7v NB (ambient: 24c) - perhaps too high cpu volts but I wanted to run quick and dirty without bsod'ing. Booted right from bios at 8.5x545 No clockgening tricks or exotic cooling.

4.6Ghz @ 1.7v NB and cpu vcore @ 1.520v



4.63Ghz @ 1.7v NB and cpu vcore @ 1.568v



Everest shot showing PL @ 12, I could run 11, but like I said, quick and dirty.



Alrighty.

wow very nice mate

i did my best bench thats on my sig at 1,78 NB air

Cheers

What bios should I use for my EP45-UD3P ? I have F4 now but is there some of the others that are better for OC?

[Zucker2k]

Thanks, Sergio. Yeah, as long as the chip is properly cooled, it can take some real voltage.

@Zucker, Not too shabby . I would love to see what that board can do with DDR3 in it. I think you should pick some up! I would go straight for some low voltage CL8 or CL7 dual channel kits made for i5 or i7.

At 4 GHZ (8x500) my DDR3 system seems "smoother" than my DDR2 system. Even though my DDR2 system will beat it in all tests and benches and is faster, the DDR3 just feels "smoother" with less "lag" if that makes any sense. I think PangingIII experienced the same feeling as well between the P45 UD3's...http://www.xtremesystems.org/forums/...postcount=2641

Thanks, mate. You have no idea how badly I want to upgrade to DDR3. I know the setup has a lot more in it, but funds are hard to come by these days so I've pushed that away for the time. I have nothing but great respect for this combo baord With DDR3, I'll be in computing heaven.

My comments were rude and I apologize to Hoss for them. I shouldve phrased it differently.
I'm not the only one who needs to chill, your harsh comments are unwarranted and unnecessary also.
Fact still remains however...saying that my NB is warm and now its not bc I put a fan on it, how does that help? Now if, my NB is hot, I keep getting random freezes, I put a fan over the NB, now its cooler, now I dont get freezes...thats results that actually mean something.

I appreciate you posting your results Zucker, thanks.

I do want to say I'm not here to call people out, but as you have admitted, your response was uncalled for - especially when he answered your call for help and gave you excellent advice. May be you wanted him to spell everything out even though imo it seems straight forward: heat + cool air = cooler chipset.

Anyway, I'm sorry if I sounded harsh myself, but your post was begging for a spanking. Accept my apologies, and goodluck in your clocking adventures.

Looks good; I plan to put this chip under water, as well as upgrade my psu and etc. so it needs some planning I'll also probably go 4GB to max the two slots designated for ddr3 on the board. I'm currently trying to hold 4.4Ghz stable, but I'm sure my psu is no longer up to the task as the +12v rail (35AMP Total) is dropping all the way down to 10.70v @ 1.3920v

to get the real benefit you gonna need a nice set of hypers to do 2000mhz cas8
on 775 no big benefit with ddr3 unless you doin cas7 1700mhz+ or cas8 1850mhz+

[andressergio]

Up to 1.78 with just a fan blowing over it?

BTW: Sergio, U havent responded to my PM

I just did mate, no need to be rude on this guys are very good ones, most of all helped me on all situations and some of then sent me things to my country where i cannot find anything good...just have to wait a bit and do tests on your own also, not every mobo its the same, not every chassis has the same air ciruculation and also temps on every room...

Cheers

2000mhz cas8 That got my mind racing....

[kagula323]

Hi. What's the maximum voltage for daily use on GSKILL PI 1200 DDR2 whitout active cooling on them and what freguencies should I expect from them?

Here is my 24/7 Work PC setup. Not bad for a $99 mobo and $110 CPU.

i got a set of ripjaws 2k with epilda bbsa chip commin in soon
i hopin for 1900 cas8 on rex alot are doin 2k++ cas7-8 on p55
first set was crap 1 doa stick n i stick only did 1850 cas 8

2.2v is safe some use 2.4v
1260-1300mhz

How much is this kit?

How much is this kit?

i paid 96can$ for the ripjaws
the elpida hypers are 240can$

Andre, Thanks appreciate it! I've noticed with these boards that less volts is actually better sometimes, expecially with vDimm. My HyperX DDR2 9200's have 2.30-2.35v on the sticker, but will not boot no matter what settings are change in bios until I lowered the volts. My DDR3 OCZ's have 1.90v on sticker and don't like much more unless I'm trying to get 2000 C8 stable, and that isn't working out yet either, but 1600 as set in my sig at 1.90v is rock solid. I know Leeghoofd mentioned once before (maybe in one of his mobo/cpu reviews) to go straight for low volt i5/i7 dual channel memory for these DDR3 P45 boards.
