Building it better then braught wink.gif and 1.55.. You tring to kill it 1.48 is max voltage for them before then degrade fast also I have lapped it and it helps the idle temps a lot so far 15*c better the ihs looked quite flat but now copper on copper is much better also I haven't actually looked at other peoples x3440 because I'll look bad wink.gif no doubts the picked x3440 do 5ghz on air plus not bad for a random x3440 from someone selling 3 of them ( sells lots of sever stuff ) like the really cheap 4core no HT x3430 plus if you can why don't you buy that 360 and build a rad box for the other 360 you'll have left lot better cooling if your pump is upto it..

Well the 1156's have soldered cores apparently I hooked it upto my phase change water chiller and damn.. 70*c delta from water to cores I think my water block isn't very good for Intel chips under a Intel burn test hottest core was 84 with 10*c water 211x20 1.52 volts stable with turbo active so guess I Gotta try fix this and maybe if I can keep my cores cool enough higher clocks.. frown.gif stupid Intel amd never got hot like you with higher tdp and more power into it frown.gif

-2 idle 60*c under load with HT

Haha yeah it was a suicide run lol. Just to validate 5ghz. I managed to do a few things on desktop. Validated. Posted it. Opened a game. Played for a few minutes then it froze, no bsod. So back to 4.8ghz 1.4v for my 24/7 OC. I have to OC my memory and GPU still.

Actually my "360" rad is actually a 120 and a 240. So I have 360mm of rad space just too lazy to say it. So with the new 360 I'll have 480mm of 45mm thick rad space in the case and could squeeze the 240 in too. I'll need to buy new fans if I run the 240 rad still, I wanna buy those 2200rpm vardars as the xtreme III is 18fpi so it would be worth it for that. But it would be in the spot where I want to mount my chillers so I think I'll go with the chillers and ditch the ek 240 rad. My PSU has a 25a 5v rail so I might just run the chillers at 5v. Or I may hook them into the controller in series so the controller ramps them up when it ramps up the cold plate but that would be at 12v so first one will get 6v and second one will get like 5.7v or something. I have a D5 so as long as I keep my restriction down it flows well, that's why I want to run those gpu blocks in parallel.

Yeah the core deltas on these chips is bad, but that's just insane, with 10*c water you should be way lower than that, sounds like you need a new water block. My old Q9550 wasn't this bad. 32nm on has been such high heat density. Still it'll be nice if you can push your OC a bit more. I might try my other g3258 to see how it scales with voltage. I really want my cold plate to be able to hold about 0*c though.

If I get all this set up right I'll jump to a 4690k or a 4790k as they should clock better with less volts and I'll have better cooling after everything is sorted here. Will need that 62mm tec block though.

My Xeon is a 24-7 suicide run even though it passed 2 hours of burn test 4.4ghz 1.5 volt 97*c it passed fine.. Loaded Google and bsod restarted then wouldn't boot had to clear bios frown.gif lol also the only thing you could do is just try all the g3258 you have try 1.5v then see if any boot then try get it stable but I doubt you'll get a 3258 5ghz stable with a good temp or lower voltage unless it's a golden picked batch that do 5 on 1.4v but then things get expensive also yea a 4770k would be good Aswell they are starting to get cheaper and your water block have you modded it? What dose the inside look like and the inside of the lid maybe you can mod it and get better temps as the edges of the tec maybe heating your cold plate?

that xeon is cooking man hahaha, I hope you can get what you want out of that platform but I guess the TDP of those chips is pretty high compared to newer platforms. I think Ivy bridge might be the sweet spot of overclockability and low heat load that is perfect for TEC cooling, ie more likely to reach 5ghz and also pretty low heat load, sandy bridge is better for 5ghz but higher heat load, haswell is similar heat load but less likely to reach 5ghz. Skylake is just too expensive but it seems like a good option for tec cooling too.

thats the funny thing, I can boot 5ghz at 1.475v, maybe even 1.45v, I can't remember now. So it's possible I just need to play with things a bit more to find some stability. play with the input voltage and cache voltage and maybe system agent, might need to play with the FIVR frequency etc. It's also possible that it's my mismatched ram that is causing bsod's.

I bought the Hardware Labs Alpha Extreme III 360mm rad. It should help me hold my temps far better. Also I've worked out a way to fit all 3 rads in plus my chillers when it all gets here, it will be cramped, but it'll fit, just. So I should be able to get away with a bigger TEC. I have my eye on a 4670k for a reasonable price. 4770k would be nice though as I use a few programs that could do with 4 cores and 8 threads.

My water block isn't ideal. I can't even mod it as I think it would make it worse, I wanted to tap a G 1/4 port in the top left of block for new inlet, outlet is at bottom right, but the inside of the block has a channel that goes right around the outside next to the o-ring, so the water would actually divert round the outside rather than going through the very high restriction micro pin structure. As it is now the water is blasted into the center of the pin structure and is then forced out in all directions and gathers in that perimeter channel then goes out the outlet, I know it won't work perfectly but it is better than modding the top. However I have thought about making a new top myself from some acrylic that has two ports on opposite sides that has a channel spreading the full width across the block but not connected to the other outlet, this way the water will flow in, spread across the full width in the channel in the top, then be forced through the pins in the base to the outlet of the block on the other side. I think I can do that with a drill press if I take my time.

this is how my block works now http://www.legitreviews.com/images/reviews/1160/swiftech_apogee_xt_014.jpg

I have revision 1 version of the top, https://martinsliquidlab.files.wordpress.com/2011/05/apogeextrev2top6.jpg?w=614&h=364 so you can see if i tap a g 1/4" port at the top left corner it will just flow around that outside channel to the outlet port and not through the copper pins, so I'd lose cooling in the center and most likely it would be very bad. revision 2 probably even worse for TEC.

The base of my apogee xt is a very fine pin matrix over about 45x45mm http://minidriven.com/BlacknBlueforIB/PoorlyMAdeApogeeXT.jpg so if i make my own top for it similar to the newer apogee xl top it should work better for a TEC http://tmz-media.com/images/reviews/swiftech/apogeexl/the_mod_zoo_review_swiftech_apogee_xl_11.jpg I want to cut channels in the acrylic like the apogee xl top but keep the pins for the full 45x45mm like my apogee xt base. If' I could find the apogee XL to buy anywhere in australia I would but it's only available as part of an AIO here, and also the pins only cover like a 30x40mm section of the base so it's not ideal anyway.

they way the block is now may actually be working okay as the water is forced out from center in all directions so it should be getting flow to most of the pins above the TEC but I'm pretty sure the majority of flow would hit the center of the base and then just flow right towards the outlet so one side of the TEC may not be getting cooled efficiently.

I ran some Cinebench R15 today, its funny, in the CPU multi thread test my cold plate temp rises a few degrees, but in the single thread test it stays the same temp the whole way through. So it's a combination of not enough Qc from TEC and not enough rad space for now. Sorted the rad space, now time to find a bigger TEC. I'm trying to work out how to order a TEC from thermonamic lol.

Do you think llc would make my chip run hot? Only 20*c hotter... I'm now 200x20 1.45v 70*c
Also that bock looks bad for a tec it's a shame you like so far away I would of made you a top for it lol mine is a micro fin base but I have an inlet 1 side outlet other side so it flows threw the whole lot evenly across but yea 1.45 I think by 1.5 you'll be stable if you spend time tuning it sucks but could be possible, also I'm thinking if I need better thermal past on my chip as only using 1.93w/m-k clu is about 2.5+ about 10*c could be gained from it also on just water cooling I'm now 8*c above room temps with the speed step thing Intel use and 58 load above room temps with a max of 80 ish more voltage tuning now..

A 545w won't even cool my cpu's to a decent temp even at max 30*c hot side at 15.56v 36.5a with a 200watt load it would be 8.36*c so kinda crap at 12v 29a 11.5*c but with them I'd still be about 50*c under load but like -20*c idle,

Just tried one of my 250w as a direct die dosnt work very well just heats up over 5 mins to shutting off 99*c

so wait, is that straight watercooling? you got 4.5ghz+ on just water? and temps are max 76*c? that sounds good? what was the problem? did you use CLU? or was it ram? i see you're running single channel there. What are your CInebench R15 scores for multi and single? I wanna know how bad I'm losing in multi to older platforms lololol. I'm at 182 single core with 1.93x multi score, and my multi thread score is at 351.

I'm using intel speedstep at 4.8ghz no worries, works a treat to stop the TEC using too much power just for general use, and ramps up to 4.8ghz instantly when required. tried with and without speedstep for 5ghz, no difference in stability, meaning there was none hahaha. But yeah I think I gotta find some tuning to get this stable at about 1.48v 5ghz. I'll throw the other G3258 in when I remount the block.

yeah the top is not ideal, but there are no reasonable off the shelf blocks for TEC's direct die. It's time to get out the hacksaws and drill press I think for a custom top as the base should be pretty good to work from biggrin.gif

I've sent an email off to thermonamic, if they respond with prices I'll let you know if it's reasonable and maybe you could snag one of their bigger TEC's too. A guy in the USA has ordered one in the past for US$70 shipped per TEC, but I've asked for one with all the specs, CuSn solder, Aluminium Nitride Ceramic etc, to make it the best TEC possible for heat transfer, so hopefully it is reasonable. Would be fun to play with a TEC that big and you might need a beast of a TEC with that heat load you are dealing with. I think one of my friends speaks cantonese so I might ask her to translate my email and send it again if they don't respond hahahaha.

I;m gonna unplug the TEC and put the CPU back to stock and run it like that to see if it tells me if my mount is terrible. technically it should all transfer heat through without the TEC on so if its say 10*c hotter than just water cooling thats about right, but if its way higher I'd say that confirms I have a bad mount and too much TIM.

I won't show you my r15 scores lets just say I'm only ever so slightly behind that 3770 wink.gif so roughly 2x G3258's and mine cost £10 less, my problem must have been the ihs was so bad it made temps horrid after lapping cpu and block then a small pee of Tim the temps droped 20*c with very cheap paste the huge $1 30g grey stuff in the huge tubes I need to either get some clu or as5 when I get some money saved up again, I'm also now at 4.5ghz 1.32v with HT on so 8 threads 75*c under load vtt 1.4 (lot higher then I'd like) ddr is at 1.51v at 1600mhz and just doing stuff it's so much faster then my old fx4100 even when that was at 5.2 it smashes it at Sony Vegas 13 I use to get playback lag now it's fine and yea I'm stuck with single Chanel I don't know why but. Either board is dying cpu don't like it or it needs 4 sticks to work as my hyper x 4gb's don't work so only using 4gb g.skill 1600 am kinda regretting buying this Xeon n board in some ways as an fx8300 only needed £30 more to buy one new but then this Intel has been fun pushing it so far 2ghz overclock is my pb on just water need my stuff to turn up so I can start insulating for my tec already
