Anyone know what may be causing this?
Thanks

I have the same prob with latest ver, 1224. ver 1212 works for me. Over half the time, I get a winsock error message when I reboot, even though ET6 launches. And often ET6 doesn't launch at all from the startup folder even though I can manually launch it once in windows. Not using ET6 isn't an option cause that's the only way to get smart fan (no smart fan in BIOS).

I guess I will give it a go then without any nozzle and see how it works out.

I had Dtek V1 with washer and 5.5 nozzle on my E8600. When I upgraded to i7, no way was I taking my loop down twice and no 1366 bracket available, so made my own bracket and left loop as is. First couple weeks, I used DTEK and nozzle on my i7.

The first 1366 that came available was GTZ so I switched to that. With same ambients, I got ~2C better on load at same overclock looking at 4, 4.1 and 4.2 by switching to GTZ with backplate vs DTEK as described above. I had probably 15 runs prime/linpack with DTEK and more than that now with GTZ, any way I look at it short runs or long runs, realtemp usually records about 2C less max temps and looking at avg temps with GTZ.

Though that is not exactly what you are asking, and unfortunately the same laziness that prevented me from taking my loop down more than 1x until 1366 was available, also prevented me from knowing what difference between nozzle on vs off, but given it was 2C from GTZ with it on, my only comment was it was not too bad with 5.5 nozzle on. But cant tell you if would be same or little better with it off, or for that matter a little worse (theory doesnt always predict results). Not to mention I made no effort to control any other variables, though my ambients are usually very controlled.

I cant get the program to open period lol...not just on windows boot and it auto launching...but Trying to open the program manually way AFTER windows is done booting...it just wont open.

sorry, but I dont have Vista installed anymore.

did you do a fresh install of W7?

updated screens: Found a little more performance with memory tweaks.
superpi at 4620 Mhz, 1.488 Vcore

^^^nice clock!!!!! and run :up:

ive pretty much given up on overclocking my rig. i have never in my life owned a setup that was so hard to overclock. I cant get 4ghz stable no matter what i do. I thought i had 3800mhz stable. It was linx, and prime blend stable for 6 hours but after 3 hours of BOINC i got a BSOD. I am running default settings now and think i am about to sale everything.

Can I call dibs? :rofl:


edit: Seriously though, this is something I've known for awhile and is why I don't spend endless hours priming and running linpack. I need my rigs tuned for boinc stability, specifically WCG. After I run a few quick stability tests, (short linx loops, fritz, wprime, hyperpi, some 3d) I set them crunching. Instability will show quickly.

its very aggravating. Too many settings to tinker with. Plus i dont like my motherboard anymore!

I wouldn't like that one either.. sorry to hear you are having issues tho. Maybe start from scratch, with a mobo that actually shows the real voltages you are setting?

im not spending anymore money on this rig besides a few new video cards. I am tired of dumping money into this bottomless pit only to be let down.

LOL! "Besides a few new video cards."

Love it. :D

yea.lol im getting new video cards no matter what. i wouldnt mind actually getting the new evga x58 classified board when its launched actually. It seems to me the E-LEET software is far superior than any other software available. I cant even find a single program that will tell me how much qpi voltage i am running:confused:

so what other encoding/conversion app would you guys suggest that's easy to setup and run ?

Eva,

480p source (ie. dvd) at best may only give you 50-60% load, resolution is too small to get any accurate data with.

Work with a 720p/1080i (deinterlacing is pretty heavy)/1080p source and encode with x264, you can do small sample encodes from a full length source if you limit the frame window you frame serve via avisynth script.

Any questions feel free to holler my way. Video encoding is one of my raison d'etres :up:

I'd definitely consider switching out the mobo once you've cooled off from the disappointment of your current one. Waiting for the second revision of boards wouldn't be a bad idea at all. I'm thinking the current boards are holding some people's chips back more than anything else. The base clock seems to be the one variable that responds very differently from board to board.

If you decide to switch soon, remember that there is a great Gigabyte thread here. :up:

the giga board was what i was initially going to get. But i ended up finding a good deal on this MSI. It was under LN2 at one time and carried a 965XE to 5.4ghz. But i am not happy with it as far as overclocking goes. It has a great layout, love it for that and its a stable board. Im gonna hold off for the EVGA X58 Classified so i can run tri-sli at full 16x. Next week will be interesting though to see how 3 core 216 260's run on the MSI board being that 1 slot is only 4x.

I never used the nozzle on my dtek v1 and I can tell you... the flow rate is a lot higher on the dtek V1 is a lot higher than the GTZ. my loop design remained the same for the most part. the cyclone is my v1 ek res is pretty weak with the GTZ in the loop by itself compared to the no nozzle V1 dtek with Mcw30 in the loop... any chance I could get you to send me your dtek mounting plate? ;)

I need it...In my favorite game ETQW the cpu usage is 75% with HT off and 35% with it on.

I don't like Evga's current X58 bioses and one thing I hate about the board is whenever I reboot it has to power down and then power back on. the Ga x58 ud5 doesn't do that. Id hold off on the EVGA X58 Classified they need to get better at bios writing first.

I would have been happy to send what I made, but threw it away, and after seeing it you probably would not want it anyways:p:. My temp "homemade bracket" was a 30 minute cut two pieces of thick aluminum strip and drill a few holes and place over the bracket that came with it....see pic.

And totally agree the Dtek without nozzle had much higher flow than GTZ. In fact the whole reason I bought washer and nozzle for DTEK was not for better temps, it was to slow the flow rate down. I have silent ddc 3.1 pumps, but without enough restriction they make a cavitation sound at high flow rates which is annoying. It sounds like air, but it is not air. But pinch the line enough and slow flow down, sound goes away. All 3 of my identical pumps do that. The GTZ has enough restriction by itself, so no water cavitation sound.

I have the EVGA x58 board and have had no issue overclocking my chip. I did do a x19 multiplier, but doing 200 was pretty easy. One thing that I read in Anand's review was that the bios reports a higher voltage than what is actually being feed to the various parts, i.e. CPU, for example, if the bios says its 1.45v vcore, it may actually only be 1.35v vcore. I have not had a chance to measure using the voltage pads on the board, but I plan on doing this next week. Anyway, my point is that a lot of people are complaining about high voltage (1.41) to get 4Ghz and higher on this board and in reality it may not really be that much, just something to think about. Shamino is one of the gus that has worked on the bios, so I am pretty sure the bios, especially the latest one, are rock solid. Granted, the Classified will definetely bring some fixes and enhancements to it, I am just saying the current board is pretty sweet. Like I said, 4.2Ghz with HT and Turbo mode on was pretty easy once you understand the relationships between the settings.

I would of used it lol... I got so many fans going I don't hear any of my pumps... in fact they are slient when I don't have my fans running.

Another personal record, 4662 Mhz superpi @ 1.4xx Vcore .
i7 920 batch 3836A977
OCZ 1600 DDR 8-8-8, 6GB
giga UD5
Tuniq Tower 120 hand made hold down
24/7 = 4011Mhz @1.184 Vcore

roller, that is phenomenal. When I get my water cooling setup figured out and installed I want to spend a good amount of time finding out what's stable and benchable with HT off @ very high clock speeds. :)

Thanks for the kind words, JWMc. :) We should keep in touch and share info about settings. Just a few days ago I was limited to 4578 Mhz, a few memory/Qtt tweaks with the same Vcore have gotten me where I am now.

For those that live in the DFW area, Microcenter has the 3841A batches in stock for the I920's. These are good overclockers.
