try 8-10-9-24 (6-6-10-100-6-1) or 7-11-9-24 (6-6-10-100-6-1)

i maxed out my 2200 pi @ around 1940mhz so i did cas6
voltage will not help much so 1.68-1.76

thanks mate didnt work seems that 4500 mhz cpu affects, at 4250 may work didn't try yet

Cheers
Sergio

[andressergio]

Yes mine passed 32m, no problem. Try 1.5v mch also, might help. What I've noticed is that, you need a little bit more mch for DDR3 than DDR2. I should have recorded all my settings, but didn't.

wish you had it mate it didnt work...seems 4500 mhz too much for them, will try 4250 but my 24/7 is 4500

cheers and thanks
Sergio

Congrats man wellcome to the thread

Dont be afraid on pushing the UD3P can handle it just be sure to have a fan over or near the MCH and mem

this i've done with UD3P + Q9650

http://hwbot.org/community/submissio...ghz_9sec_450ms

and this with UD3P + X3380

http://hwbot.org/community/submissio...380_9sec_234ms

all done with a thin 3 fan HW black Ice360 rad and dtek fuzion block

Now i moved to the EP45T USB3P that i love it with a bigger rad an nicer block, still didnt bench it waiting for some mem to arrive

keep posting
Cheers

Wow man, nice results. What voltages were you pushing on the board to reach that fsb?
I cannot for the life of me post past 535fsb, I've got voltages pretty high aswell.
MHC 1.5v, CPU Termination 1.5v, PLL 1.6v, ICH 1.2v, and the cpu vcore has been as high as 1.55v. Dropping the multi down to X6 doesn't help me post past 535fsb either.
Got 120mm 60cfm fans close to the mch and another 120mm fan on the memory, with a household fan blasting into the side of the case.
Temperature sensors have started working on my cpu when I pass 50c and load at 4.5ghz under P95 was 58c.
Any suggestions are welcome, possible that I just got a subpar board?

Very low chance it has to do with the board, but it's possible. I had trouble getting 500 FSB on my Q9550 on the same board (look a few pages back). Just takes some tweaking and most of the time it's just one little setting that needs tweaking that you probably will miss to completely stabilize properly (For mine it was bumping a clock skew up only 50ps). I learned my lesson quickly about quads and their fussiness at 500+ FSB. They really put up a fight unless you beat them to death with baseball bat

For you, it might not be the same as me for above 500 FSB but I would try other settings rather than seriously overvolting everything. 1.5 VTT is really high and can easily damage components and you shouldn't need any more than 1.4-1.44max VTT even for that high of an FSB. MCH should be fine up to 1.64 or so with good cooling and don't push PLL past 1.7 as it will end in the same fate as VTT. You don't really need to mess around with ICH unless you have 6+ Hard drives so I would leave it.

I would start messing around with the CPU/PCI-e Clock drive voltage and CPU/MCH Clock Skews, most of the time they really help. Maybe try your ram too with higher voltage and/or a divider with lower FSB just to rule that out. If it's not posting then maybe it's something to do with the PL (Performance level) in ram settings. I found that higher FSBs need it to be loosened slightly or else my system wouldn't post. Oh yeah, one last thing, reference voltages, play around with them, especially MCH and eventually CPU once you start cranking that multi up. If you can get the system to post then just work up from there.

Maybe post a template of your settings too? Just look back a few pages and you should find some then just fill it in with yours.

Thanks bud

I have no second bench rig so i used my 24/7 system i just did this:

in a cold day of winter like 13C entering from the window my ambient inside was 22C





on summer where temps outside where 30C used my portable AC to push same temp to the rad 13C





and today with the new case and things i can do the same on ambient without the need of AC or cold air



I agree with Dark Energy that no need to push if you not willing to bench, i did it so my mates OC Nub, Jor3LBR, radaja and so others pushing volts but always be sure that temps a good, wont harm to bench i've used 1,6VTT, MCH till 1,7 etc...my mobo quad after 1,5 years still rocks still same tests

If you willing to play some i can send you some templates

For my 24/7 settings i use MCH on 1,46 / VTT 1,36, but im going to up that soon and wont harm

Cheers

Nice rigs and nice results!
I've got a portable AC unit not doing any work so I should be able to put that to some use on the weekend.

For 24/7 settings I already have 4ghz dialed in with super low voltages. 1.3vcore, 1.2MCH, 1.24 VTT, all other voltages stock.

I'm looking to do some serious benching now, 2D mainly, but I might give my old 3870 a few 3D runs aswell. Really looking to push this board to it's max, without blowing money on chipset waterblocks.

Back at 4ghz now working my way up to higher clocks with ambient air. Feel free to send over some templates, I'm ready to play

EDIT: Is any more radspace going to help with keeping temps down or just restrict flow?

didnt get your last question can you explain plz

Sorry mate should have explained better.

I currently have a 120.3 rad cooling my cpu, will adding another 120.3 rad into the loop help keep temperatures low at high voltages, or will it hurt flow rates/ just make no difference?

Well i think you should post on the liquid cooling section as i think it will restrict flow and temps will not be such lower but maybe im wrong, it also depends on the rad type. Those pis i showed you the first 4 where on my old water cooling system wich was HW Black Ige gen 2 360 wich is a thin rad and restrictive but more fins so i used power fans, a dtek fuzion v1 block and the gtx285 volt moded in da loop same pump

now i use HW Black Ice 360GTX + Apogee XT + EKtop rev2 for the pump sharing again the GTX285 and my temps went down dramatically at load so much that i linxed at 24C ambient

here's some shots of da fat boys when i was building

Just about done with the loop, just waiting on fan controller. BIG thanks to Sergio for helping me along the way.
He is a good friend!

Thanks my friend

Nice job and well done now you will never go back to air

Hope you enjoy it very much

Congrats

[OC Nub]

Nice job with the new WC rig.

Thanks again Serg.

Nice job with the new WC rig.

Thank you very much. Still have some work to do but minor.

[jjjc_93]

The WC rig looks fantastic NoGuru. I'm loving the koolance rad mounts, look much better than the plastic swifty mounts.

Thanks! As soon as I seen Sergio's I decided to build the loop, lol.

[In-Fluence]

Nice loop Noguru. Is the Rad an XSPC?

[MrDucky]

now we want to know the temps noguru

[jjjc_93]

Finally booted into windows at 4.6Ghz and the psu blew. Damn murpy's law
Going to see if I can get a decently priced replacement tomorrow, and get back to the overclocking.

I also want to know your temps noguru

jeeeze man how come what PSU u where using

[jjjc_93]

jeeeze man how come what PSU u where using

A rebadged 1000w Xilence PSU. Yeah I was asking for everything I got, but funds were tight and this psu got the job done for nearly 2 years.
Will be looking at getting an 850 or 1000HX this time round.

[NoGuru]

Nice loop Noguru. Is the Rad an XSPC?

Yes it the XSPC RX360

now we want to know the temps noguru

Blend stays around 55c I forgot to check the NB at load, but it idles at 42c and the
5850 stays at 41c in Furmark that is amazing to me.

Opps, just seen your post.

get the HX850 hella PSU

[radaja]

NoGuru,very nice WCing build.looks like andressergios and yours and mine are family.
all gigabyte,all blue and all look great.

Thanks radaja! Sergio helped me build the whole thing except the blocks, I bought them used about a month ago.
Might have to do some blue LED's too.

[In-Fluence]

Agreed, HX850 (or 1000 if you've got the room). I've heard the 850 can manage up to 1000 anyway so probably a little more bang for your bucks

@NoGuru - nice - the XSPC rads are probably the only worthy competitor to the thermochills from what I've read, and the big fins are great if you're after a quieter setup, plus the price is reasonable. I think my XSPC pump is probably suffering a little now though, so I'm thinking of going for a dual loop reservoir and a single laing pump next. After that I may build on a bit more GFX cooling and mosfets when my USB3P arrives. I think I've fathomed a way to fit it all in and around the case and can probably make room for another 240 rad at least, but it's so heavy already I probably won't be able to lift it with yet more addons & water!
