Phenom 9850BE low voltage overclocking results!

Koo, did you see the 790GX boards are finally making their way onto Newegg!!!!!!!!!!!!!!! Ken just posted that Gigabyte has their board officially for sale!

WAHOO! Now where are the rest of them...I'm getting really really excited now c'mon! H2O can wait a bit.

K <--- is really happy

This should answer your prayers, though I'm not sure about the price yet. I imagine it'll be within a few dollars just like when Gigabyte brought out their 780G board (the hybrid crossfire board) and ASUS matched them again.

Those two companies are after each other lately and wait til the very last second for the other one to make a move so they can match. I expect the ASUS board on the site tonight, maybe tomorrow and that's the one I'm waiting for. DFI also has some boards coming which also interest me.

Yea the 8 pin was one of the first things I looked for when the boards were announced. I think it'll be okay considering what the Foxconn board could do as far as overclocking, we all know they aren't known for making the best overclocking boards so no worries.

All of the boards have already been shown at Computex I'm just waiting to see the pricing. The 790FX boards with the SB750 should be out as well as they're both slated for release at the same time for those that want that instead.

As for the 8x PCI-E lanes, I don't mind since I'm using a single card anyway plus 8x really isn't a big drawback considering how much bandwidth we have anyway. I've seen a few reviews of the difference between 1,4,8,and 16x and you really don't notice anything until 4x so we're more than good.

K

Oh yea, as for the 3 video card slots...it's not a first as DFI did it with their M2RS 790FX board as well.

K

Yea Cracker said it drops a little performance so I'm gonna test that now. Be back in a bit...

PCI-E Lane Width testing

Okay so since we've got a few people worried over the 8x vs. 16x Lane Width difference when using Crossfire X on the new GX boards I decided to do some testing to try to help clear things up.

I used 3dmark06, Furbench, and GTR2 for testing the difference Lane Widths...

I'm convinced that it will make little to no difference when going from 16x to 8x lane width after my testing. Please remember that the only time you'll be locked in at 8x is when using Crossfire so those who use a single card shouldn't even pay this any attention as it matters for you even less.

I've attatched 4 screen shots (2 3dmark and 2 furbench) so that you can see the difference in scores between the two settings. I did not take screenshots when running GTR2 so you'll have to go on my word for the results.

I ran my usual GTR2 personal benchmark of...

Saved replay at Spa 2003 track with full in car dash view
AI Driven cars to remove human input changing the outcome
My AI car starting at the back of the Grid to ensure that all cars can be seen
100% Full details on every option in the game (including all Advanced visual options)
16 cars on track
23:00hrs gametime (full on night time)
100% rain weather
4xAA
16xAF
Adaptive AA
Triple Buffering

The benchmark is done with FRAPS starting as soon as the cars get the green flag and automatically ends 180 seconds after starting. The final results for the test were as follows...

PCI-E 16X ----- PCI-E 8X
28fps --------- 29fps

That shows that even ingame the difference is highly unlikely to be noticed. 3dmark06 results were only 44 points higher with 16x setting. Furbench results were only 9 marks higher with 16x setting.

I hope this helps those who are wondering/worried about choosing one of the 790GX/SB750 boards over the higher priced 790FX/SB750 boards.

EDIT: All 3dmark06 and Furbench tests were done at 1360*768 resolution.

DAMN VIS! You're like a shark! That has to be the quickest reply I've ever seen!

K

Btw, glad I could help.

Final Assurance...PCI-E 4x testing

I figured since I said you'd only notice a bit of difference when running as low as 4x I may as well add some fact to that statement.

GTR2 results for the exact same benchmark outlined above...28fps (lost 1fps )

3dmark06 and Furbench results are attatched to this post as well. For those that only use their controllers/wheel/keyboards to play benchmarks you may wish to skip these boards. For the rest of us that play games and do other things do not worry...pass go and recieve an awesome board. (monopoly pun intended)

I'd say 1.35v is about all that'd be needed, but depending on the clock maybe more. Here is a very old screenshot of doing 3.1Ghz testing with Kuma (excessive voltage as I just wanted to get a test in and not worry about errors).

K

Sweet...nice trend going over at newegg. 790GX board #2 listed from Foxconn, and this one is cheaper! Also is it just me or does this one look like it means BUSINESS!

Thank you! Also, would you know why my mobo is at 44C??? i've got everything at lowest volts...wtf??

Holy wow batman! Are you sure you didn't mistake an option in the bios for something else and set the voltage incorrectly? Do you have any fans not running ummm....anything different? My board has never been that temp no matter what settings I've set, as a matter of fact I believe the highest I've ever seen my board at is 38C period!

Maybe whatever program you're using just read the temp incorrectly is all.

K

Weird, maybe there is a setting that's incorrect in the bios or something because that's indeed higher than any temp I've seen. What is your temp normally?
