Testing & Performance
Test Setup

CPU AMD Athlon 64 3200+
MSI K8N Neo4 Platinum BIOS 1.B
2x 512MB Crucial Ballistix
Sapphire X1800XT 256MB
Antec Super Lanboy
Tagan 2Force 480w

BIOS Settings

Stock CPU  Overclocked CPU

For the temperature readings I used MSI CoreCell.  To put load on the CPU, I used Prime95.  Look above for the exact settings I used for overclocking the CPU.  RAM was 1:1 at all times.  (Stock, left.  24/7 OC, right.)

In-place large FFTs used for all testing.  To test load, Prime 95 was run for 10 minutes.  To test idle temperature, the computer idled at desktop for 5 minutes.

XP-90 Testing

2610MHz, 1.54v vCore

(Idle, right.  Load, left.)

2010MHz, 1.40v vCore

(Idle, right.  Load, left.)
Ultra-90 Testing

2610MHz, 1.54v

(Idle, left.  Failed, right.)

The Ultra-90 failed prime.  Why?  Remember that ram fan I had to rig up earlier, that was without it.  No worries, it passes as soon as I get a breeze on my Ballistix.

With a fan blowing on my RAM, the Ultra-90 excelled, beating the XP-90 by a full 2ºC. 


Same exact temperatures.  Impressive!

As soon as the heat load increases, the Ultra-90 shines.  Cooling my 3200+ Venice a full 2ºC better, when heavily overclocked.  This is most likely because the Ultra-90 has 2 more heatpipes for a total of six, vs. the XP-90, which has four.  Heatpipes transfer heat from the base to the fins much faster than a regular "fins-on-base" styled heatsink.

Not too bad. However, this review seemed fairly laid back or something, much more casual. Not necessarily a bad thing. Also, when talking about test setup and method, you should say how long you let it sit for idle and load. I know you photoed that into your screenshots, but I prefer it all being stated before the testing screenies. That's personal preference though. Besides that, nice job

Edit: Upon a more thorough reading, I'm sorry to say I've come to dislike it You misspelled necessarily and necessary. I really feel you should spell out everything fully instead of using all of those abbreviations. You should have capitalized Ballistix. The overall organization seemed off and it just doesn't seem to flow. This is not a flame or anything of the sort. I just have a bit of a habit of stating things very bluntly.Quote

I'm going to have to agree... The review only took a couple of hours for Nick to fully test and complete, doesn't seem long enough to be a solid official review.Quote

Review taken down for a bit of moderation. Will be back later.Quote

i dont think its too bad, idle and load times are shown nicely in a graph Quote

I think I corrected it all, and I re-enabled it. Take a look
