I didn't have the board at the time, so could only look at pictures. Have done a bit of research since :-

1) Thermalright Bolt Through
There is as George pointed out some interference. It isn't to noticeable but does give cause for concern

2) Scythe Universal Retention Kit
I'm lucky 'cos I had a couple of these kits

The backing plate on this very rigid steel , seems firmer than the Thermalright, but it also has an equal depth layer of neophane with a final layer of paper on top.

Side view showing the 2 layers.

I'm using 1 with my EP45 & my Fuzion block. A 2nd works well with the XIGMATEK HDT-S1283 on the EP45T.

This shot of the baseplate after unmounting, shows it's working pretty well
Gave a good impression anyway

very nice!...your pictures would take a big load off anyone's mind to know they can get around this problem.

Hi Ace,

very nice!...your pictures would take a big load off anyone's mind to know they can get around this problem.

That'll be good, but I don't think its's a big issue the plastic chips feel very solid are are aligned , are capable of taking pressure as
Alcibiades

I installed a Thermalright Ultra 120 Extreme on the EP45-extreme and the EP45T-extreme using stock everything, I was not gentle either when mounting those spring loaded screws, but encountered no problems at all.

and I found initially. It's good to know there are options if you are concerned. Nothing to stop you cutting a Neoprene Rubber gasket to use with the thermalright bolt thru

565x7.5@2.0B 1,130 5,5,5,24

These last 2 clocks have been a bit odd, I started off aiming at 480x7.5 , but struggled to get ram stability.
With this clock I've dropped MCH Reference to 0.756. so the 3 Gtlrefs are now 60.6%, 63.3% 57.3% CPU Reference1, CPU Reference2 & MCH Reference

hmmmm, the Biostar TPower seems to be a VERY good board...it was a slow start to figure out the bios settings...i think i have it down pretty good.

the board comes right up to being neck and neck with the X48T and i am only running the VC at 8X link speed since i have an Areca Raid card in the 2nd slot running at 8X.

That's looking good Ace

that 32m Pi looks a real good time.

**Ace-a-Rue** · 06-08-2008 02:45

yes!..the 32M surprised me...the board just gives you that burst of speed...i am going to put the other drives on the areca card; the ones i used in the PCMARK 2005 showdown between the X48T and IP35 Pro to eliminate any doubt about its true performance...i want to make sure the Veloci-Raptors are not adding an extra burst of speed somewhere...you wouldn't think it would except in the PCMARK 2005 bench...the video benches and SuperPI should stay the same.

**supershanks** · 06-08-2008 10:55

Looks good Ace, looking forward to see how it goes

**Ace-a-Rue** · 07-08-2008 03:34

i am trying to see if i can run a stable 530 FSB at 8X...still working on it!

Aye think 510/520 was top on x48t ?? I've got 533x7.5 on this , will have to give it 0.5 more if you do

I'm sure you'll get there
