Overclocking Comp mk2 is go!!!

[fhpchris]

OK mate, cheers for letting us know

Guys, only a few days left to get the benchies in!

EIST is enabled, so at idle this cpu has a multi of 6, but its normal multi is 13.
13*233=3030mhz.

All are done same ram speeds and same cpu speeds.
25% are tweaked and have different gpu and video card ram speeds.
Full are full tweaked and clocks on GPU...

Drag scores:
3d01
40276 / 27816 = 44.8% increase over stock
3d03
20809 / 10243 = 103% increase over stock
AM3
117351 / 86305 = 36% increase over stock

Well here goes

01 Drag @ 77.4%



03 Drag @ 91.7%



Aqua @ 113.7%

WOAH :| *falls over* AWSOME scores mate amazing work

Good results, but I am suprised that you cannot get a higher % in 01 over aquamark.

My rig is not crappy enough to score that low, getting 77% in 01 or 100+% am3 isnt even possible for me

[sparkY1000]

Yeah I really thought 01 would be my strongest benchmark and that 03 and AM3 would be my weaker benchmarks, but when all the tweaking and overclocking was done I was amazed by 03 but nothing prepared me for AM3!!

I had so much fun I thought I had pushed the card before but now I really see what it is capable of! I know it isnt a £300 monster or anything but for £40 I dont think you can complain!

[fhpchris]

I will not feel bad comming in second place to you, but I wish you would give me a chance at least!

[don_vercetti]

Fwiw, i am gonna be too busy for the forseeable future as well. I've got training for rugby over the next few days. So sorry, but i won't be putting forward any results.

best of luck to everyone else.

[jimwah]

Sorry, but I' not going to have enough time to get results in either. I've got to move at the weekend, you don't realise the amount of junk you own until you have to jam it in boxes & stuff it all in the back of a transit. Enjoy the comp :thumbsup:

Nooooooooo. Im gonna be doin my watercooling next week, cant really vmod g card till then

[SoddemFX]

The card set up in the system, insulation was proving very difficult so I didn’t bother. Let her freeze over!

The temperature of the GPU was held at roughly -50C by a small homemade single stage vapour phase change cooler charged with r404a. The GPU voltage was 1.95v, a few days previous I had ran ~2.0v which resulted in the output inductor de-soldering itself when running at over 300MHz clock frequency, hence the slight “back off” on voltage.

Whilst benchmarking the temperature of the memories cold plate was fluctuating between -17C to -13C, indicating that this memory at 4.00v and up to 610MHz was putting out a reasonable amount of power for only eight memory IC’s…



My favourite bucket, I estimate that the four 30W peltiers and the load of the memory was in the region of 160W. Over the course of one and a half hours I had to siphon out and refill the bucket 12 times as the water temperature rose. The water block temperature never exceeded 30C.



There were a few millimetres of frost over the memory cold late. I knew that with running un-insulated I could not power down the peltier or vapour phase change system due to the thaw and subsequent damage to the card this would cause. Because of this the system remained powered until I had finished, which was a pain in the...



Protection for the motherboard courtesy of a plastic carrier bag, Morrison’s is an overclockers best friend

At the end of the benchmark runs the cooling systems were turned off and the card allowed to thaw once removed from the motherboard. Water quickly began to drip down the card as the ice melted.



3DMark2001 was run first using the 40.72 drivers and DirectX 8.1, LOD 10, 12, 4, 3.8. The first trial run was at 250/620MHz to test the memory performance under peltier cooling as I had not tried this before on this card, after a few runs it became apparent that the memory was degrading with the high Vdd being used, the remaining runs were done quickly as I was loosing about 5MHz every 20mins. I ended up running at 303/610MHz, I could have gotten another 2MHz from the core but I wanted to be quick:



Aquamark3 at 305/610MHz was run with 40.72 drivers and DirectX 9.0C, LOD at 10 - by this time the memory was beginning to artefact slightly:



3DMark2003 at 305/591MHz was run with 66.93 drivers and DirectX 9.0C, LOD at 10 - by this time I had a few bad runs and with the memory rapidly going the way of the dodo 591MHz was the best I could manage:



Interestingly with the memory at 500MHz and stock memory voltage I was able to run the core frequency to 320MHz, perhaps this PCB didn’t lend itself to combined high core and memory clocks, or perhaps it’s something within the GF3 architecture… who knows…

This Ti200 was a good card core wise reaching 260MHz on stock air but quite disappointing considering it used 4ns memory. The maximum memory clock achievable on stock air was 500MHz with slight artefacts, which is poor for 4ns IC’s. Cooling and massive over voltage on the memory together have given a great increase. After the benchmarks were complete I played with the card until the memory was falling below 550MHz at this point I decided to pull the plug, I don’t think it’ll work again –and I don’t mind

With an average over the three benchmarks of 77% I think the old girls done a grand job.

Never surrender!



2001 = +69.4%

2003 = +64.8%

Aquamark = +97%

Average increase is +77%

im not gonna be posting up scores either.
i thought it would be possible with my school schedule, but school takes a lot of your time (f cal bc, bio2, phys2)!

[Highland3r]

Closed to new entries now guys.
Thanks to those who participated. Will get the results posted up later today

Cheers

Yea sorry, just sorting them now... :blush:

[Highland3r]

Results


Congrats to Sparky for edging chris out by 1 point, and grats to Tom for taking the win in the "other" cat.

Thanks to everyone who took part, can you all drop me a PM please and we'll sort out the prizes

Will try and organise round 3 of the comp at some point, need to make sure its better organised etc than this round though!

Cheers guys

[sparkY1000]

Well done everyone! Was a fun competition! Congrats to Tom for winning the "other" category and congrats to chris ur 03 was impressive

Thanks to Highland3r for running yet another good competition

[fhpchris]

Good job sparky! There was no way I could touch you in AM3 or 01!

Thanks to Highland3r for running yet another good competition

Yep!

[SoddemFX]

Good going guys,

Thanks to Highland3r for organising this

Cheers!

Tom

[Charles Wirth]

Yep, thanks for staying on top of things. Good to see all the effort going into organization and following through.

[Highland3r]

Cheers guys.
Will hopefully be back again for the 3rd round, maybe a new format... who know's!

Thanks for all the support and a huge thanks to all the sponsors too

im not sure what drag means so!

I'll edit post after I done the other benckmarks

[-Acid-]

i wanted in this but was late so i deffo up for the next one

[[cTx]Philosophy]

At first I thought theres no way anyones gonna be able to do this, and now im shocked, ppl have gotten ownage % over stock..

Id never be able to get this kinda results with my conroe and GX2
