I put a little thermal compound on the CPU and used a piece of a clear plastic bag to smear it all over the CPU as thinly as possible and also did the same for the heatsink.

That's how I normally apply AS5 here. I have also tried the ' grain of rice ' method, and spreading out the paste until you can almost read the writing on the IHS. Difference in core temps@load didn't budge.

Lets see how the Ultra120 does tomorrow.

Sean, what was the highest you were able to get and at what volts? Was there any chance of for example having it at higher volts to get 3GHz booting into Windows etc?

Hi, yes one would boot at 3ghz, the LCB9E with 1.425 or 1.450 cant recall exactly, very unstable though.

Will be interesting to see how well it performs compared to your current cooling.

Mine is like that too at such volts and to get it 3GHz stable requires only 1.525v. ;)

Ah i see, well since they were'nt my PC's then sticking close to stock volts was ideal. ;) Still thats quite an increase imo, would'nt like to run say my 4800+ at such levels day in day out, thankfully 3ghz almost at stock volts. :cool:

Yeah. The Scythe Mine has been fairly decent, as long as you use a 120mm fan. I'm sure the 120 will knock the temps down another 3-5c at least. If it does then I'll be fairly happy esp considering the weather atm :)

Currently the E6 LCB9E is running at 2.7ghz but it needs 1.41v to get there, which is exactly the same speed / vcore as my E4 LDBFE.

Odd thing is, neither of them so far will do 2.75ghz stable with up to 1.475vcore, at either 250x11 or 275x10 ( ram on 166 / 133 divider respectively ), so maybe my motherboard just doesn't like those fsb / divider settings... Might try 300x9 just to see if it can cope, which I doubt ( A8N-SLi SE )
 
I have an LCB9E 4800+
2.75 (1.35v)
2.85 (1.4)
2.95 (1.5)

posts at ~3.1 with just 1.45v O.o but needs ~1.6V to become stable at 3.0 (temps sky rocket at that voltage)

- cores are about 2c apart, but high temps load (~60)

Well, so far I'm not too impressed. No drop in temps whatsoever compared to the Scythe Mine+120mm fan. The Ultra 120 is mounted blowing into the bottom of my psu because of the socket orentation on my motherboard, whereas the Mine was mounted blowing towards the rear case fan. My gfx card is a Gainward 7900GS, so not the hottest card out there.

X2 [email protected] / 246x11 / 1.4vcore

Case side panel off

Ambient temp - 19c

Ilde temp in Speedfan's K8 sensor after 10min from cold boot.

Load temp in Speedfan's K8 sensor after 20min running Orthos Gromacs test@pri 9

Scythe Mine+120mm Evercool 80cfm fan@100% ( As5 cured for 20-24hrs )

Idle 29-30c Load 47-48c


Ultra120+120mm Evercool 80cfm fan@100% ( As5 cured for 20-24hrs )

Idle 30-31c Load 49-50c

Ultra120's mounting screws are turned as far as they'd go. Going to try reapplying As5 again, and also using the S-clip with the Ultra to see if either makes any difference.
 
Just reapplied As5 45mins ago and mounted the Ultra using the S-clip so it faces the rear exhaust fan. So far idle temp is 1c lower, and load has dropped 3-4c to 45-46c after 20mins in Orthos Gromacs test.

So I guess I botched the first As5 application. Just ordered CoolLabratory Metal pads, so I'll test them with the bolt-through mounting when they arrive.
 
I suspect the temps would scale well for example 1.5v or even higher probably wouldn't increase the temps all that much. At load is the heatsink warm or very hot or reasonably cold? Also what about the core temps differential has it changed or are you still seeing a big difference?

My X2 4200+ at 3GHz with 1.525v in the BIOS although CPU-Z etc shows very stable 1.472v and I'm not sure if it's vdroop or just bad reading from my DFI NF4 Ultra-D. Load core temps are 57c/57c with a TT Big Typhoon (non-VX). The BT seems to be real good as the heatsink doesn't become heat saturated (just gets a little warm) and yet the fan is very quiet. I even have my two case fans on 7v making them virtually silent and my Corsair HX520W fan is virtually inaudible too. I've got a HIS X1900XT ICE Q3 which is also virtually inaudible.

EDIT: Also will be interesting when you change to bolt-through mounting as it probably will make a significant difference.

The heatpipes and fins are slightly warm to the touch. I'm going to leave it running for 1hr and see how it feels then.

Still the same 10c difference@load. At least it's better than the other X2 which had a 14c differencial@load.

The cooler of the 2 cores says its idling 1c above ambient :rolleyes: so I'd say its temp sensor is well out of whack.

It didn't, as my first install was bolt-through mounted. I don't think I got the As5 application quite right though.
 
I've rebuilt my PC in another case and I've used the VX model of the TT BT. I'm seeing a 4-5c difference in core temps at idle and at load. The bracket thing for fixing onto the retention bracket is so useless so will swap over to the bolt-through tomorrow.

Also the main reason for posting is I thought I'd mention the problems I had getting over 2.8GHz initially. My DFI NF4 Ultra-D memory settings are complex and when I was first trying 3GHz it wouldn't even get past the BIOS screen at 1T but would boot into Windows at 2T although it wasn't very stable. So I read all about memory settings for the DFI and tried various settings I found online for various memory and eventually I was able to get it working at 3GHz and 1T.

So basically I'm thinking your overclock might not be limited by the CPU. I suspect the memory controller is fairly relaxed about memory settings when it's not being stressed too much but when overclocking further the memory controller likely can't cope unless the memory settings are optimal.

Another thing to remember is when using a memory divider the motherboard configures the memory settings at that rated speed. So if the memory should be at 2.5-3-3-7 for DDR400 and 2-2-2-6 for DDR333 then when using the 333 divider the motherboard will set everything according to the 2-2-2-6 timings when a memory setting is left on Auto. The additional memory options (some boards have 10+ memory related settings) are no doubt also configured at the DDR333 rated timings making it a problem to leave anything at Auto when using a divider.
 
I make a point of always setting the ram manually :). It's just 2x1gb sticks of KingMax PC3200 spec'd at 8-4-4-3-1T@200fsb, but will do 6-3-3-2.5-1T@215fsb with 2.8v if needed. I tend to keep it at 8-3-3-3.0-2T until I can find the cpu's max clock anyway, then worry about tight timings.

Going to unplug 2 of my hard drives+ cd-rw tomorrow to see if its my psu that's not helping ( 480w XClio ). Also checked a few forums for LCB9E clocks and it appears that most 4200's and Opteron's with that stepping do seem to top out around 2.7-2.9ghz so I can't complain as it runs cooler than my older chip, which always helps in the summer :)


Also currently debating whether to change to this combo instead :

http://www.xtremesystems.org/forums/showthread.php?t=136051

Found somewhere in the Uk that sells the TForce 550 boards, so that + cpu + Geil ram from OcuK comes to around £160, which I'd get close to if I sold my current cpu/ram/mboard....
 
I'm about to buy and build an AM2 setup for a friend but I have little knowledge of DDR2 setups or the AM2 boards. Is it ok to run the memory with a divider and do you know of any other boards that overclock well (at around £70) as I've looked for that TForce 550 but can't find it anywhere.

TIA! :D

I have a LCB9E 4200+ Orthos stable @ 2.8Ghz 1.5v. Orthos will run for 12hrs no problems, I have had to drop the RAM to T2 to get it stable.

I am using an Infinity cooler in a P180, occasionally the computer will just power off completely, any ideas.

Is this the chipset overheating? I'm totally confused. Orthos & OCCT stable, I can game for hours then, puff off it goes.

I have a new OCZ 600W PSU and a foxconn NF4 board, could it be this board is flaking out? RAM is G.Skill HZ 3200 2Gb.

Any thoughts would be great.
 
Did you run Orthos blend test at priority 9? I suspect the memory controller or ram is being stressed too much as it should run 1T just fine with optimal settings. If it is the memory you can try changing the Max Async Latency and Read Preamble so try MAL 9 and RP 7.5 or 8. Also if you can change tRRD change it to 3 if it's currently at 2. You can download A64 MemSet (google it) to see what your current settings are.

I don't know much about AM2 setups either, but going by that thread they seem to be using 667mhz ddr2 with the TForce board / 400 / 533 divider with no issues. The ram below from OcUK looks an ideal match, and its damm cheap :)

Edit ; When XtremeSystem forums come back up, check their AMD section for a few threads on good overclocking AM2 boards.

I checked over there cheers for that. :)

I also tried to find reviews of the Biostar 570 Ultra based board but only found one but I was thinking it might still be worth going for too.
 
Thanks STR, great tip on the A64 tweaker for memory timings etc. I changed the settings as you suggested and backed the timmings down a little. Now running Orthos small FTT stable 4hrs, and going strong. Looks like it was the memory controller flaking out. Got the command rate back to T1.

Thank you very much indeed. By the way where are you in Edinburgh, I stay in Portobello!
