oops. i feel quite guilty now but wednesday i'll be

I would keep the Giga as a back up man. I know I'm deffo hanging onto my original 8320 and Asrock when they are replaced (the company who sold me the cable extension has it all for testing, but the board was totally FUBAR).

CHVFZ is a fantastic platform for next gen. Loads of PCIE bandwidth too, so loves having multiple GPUs inserted into its bottom

I guess it's best to think over a year it's under 50p a day. It makes expensive things sound less expensive

This is catching. I've only just gone and done the same . Quite a lot off the original price too (wife gets 10% off their stuff due to her work + 2 % off using a certain cashback site + 3% off using a certain credit card that refers to people across the pond going very fast).

God damn they are good looking boards!

Least cryptic clue ever

Although I am now using a crosshair V formula, I started with an M5A99x evo rev. 1 for my FX8350. This was good for overclocks at least up to 4.8Ghz and I was clocking 5GHz for many benches.

I was able to do 10 consecutive runs of 100Gflops+ at 302Mhz bus x 16 = 4832GHz with 2400MHz HTand NB and 2012Mhz memory on the M5A99x.

I would recommend at least a sabretooth 990fx or the M5A99x for good overclocking.

Thanks for posting this, I'm having a go at a high FSB, low multi on my M5A97 now, see how I get on

Yup stunning tbh. They're pretty much your Rampage for AMD. The features they pack are just off the wall too. More options than you can shake a stick at

Nice to see a man with an Intel rig having some red fun

Let us know how you get on

Would be nice if they confirmed SR will be supported/carried over with AM3+ socket then your right people can invest in a top line board.

Well I think 4.9ghz is the sweet spot for my cpu. Managed to bring down the voltage to 1.5v, going to try bring it down a little further.

5.04ghz is possible but it doesn't feel 'right' plus it randomly crashes in BF3. When I get chance will add a few more fans to see if this helps but 4.9ghz still aint bad!!

4.9GHz stable is outstanding for your board. With the Sabertooth you'd get higher clocks, but it wouldn't be a big difference.

Maybe we should do some consolidation of hardware into statistics so we know what boards capacities are. If say the UD3 only gets 4.3 then that would be useful information for someone browsing the thread.

Table:

mx0range, UD3, stable 4.4
mx0range, CFZ, stable 4.8

etc

Great Idea Th0nt would give a clear indication of whats capable.

We'd need it updated on the first post in this thread I think.

 

[gpuerrilla]

Anyone fancy skimming this earlier forum thread to add more? I gotta go bank and do a tip run.

Good idea. My ud3 revision 1.2 is stable at 4.7 with a max of 4.9 which lasts long enough to get through cinebench

 

[ALXAndy]

Asrock Extreme 3 will do 4.2ghz. That was the limit.

Can see my board and specs in signature and is prime stable.

It does 5.04ghz for Cinebench.

Don't forget your pics lads

I'll get some of mine later

My 8320 is stable at 4.5 ghz on UD3 rev 3.0 but throttles after 10 "standard" cycles of IBT. With fans on the NB and MOS Heatsinks, that extends to around 20 cycles of IBT. Technically I think the UD3 is "stable" at even >4.5 ghz frequencies but throttling likely to happen earlier.

Will post what happens with the CVFZ later in week.

Might be useful if the first post is edited to recommend boards, and to warn against buying the 4+1 boards.
