My reply to him was to show booting into an Overclock and being Stable are to far different things.

As if it's really necessary to make that distinction on an OC forum. rolleyes.gif

Is your board an R2.0 Sabertooth? If it is, you and me need to talk settings! biggrin.gif

Any thoughts on the ram ? It was the only 1866 ram my local puter shop had that specified it would work on AMD platforms .

That RAM will be great. Let us know how it goes with the SSD and all the other parts for that matter!

My guess is that FX does not have this bottleneck. If you have a Pipe, and you're only using 80% of it, will making the pipe bigger help?
This of course does not explain why linking HT and NB helps, but I don't even have a guess for that one. Maybe it's a timing thing.

And the Deneb got very hot with the NB up @ 2000MHz. In fact, my OC'd 965 ran significantly hotter in this machine than what I see so far from from the 8350, even with the FSB OC'd. Although I admit that playing with this particular OC setting was fun.

I also observed as I started into my first OC session that with completely stock settings, HT = 2600 and NB = 2200..the measured Cinebench 6.83. When I increased CPU Freq from 200 to 250, BIOS linked HT and NB as you said. With the value at 2200, performance was worse. At 2500, I think the CB score was about the same 6.8, give or take a hundredth or so.
For the CB benchmark, the only way to push the number up was by increasing the overall system frequency.

A few more quick observations. For stock heatsink with a 4.5GHz speed, temps gets overrun at full throttle using Prime95. At 4.0GHz speed, the temp tops out at 50C. Vcore had to be increased in the former case to keep the system stable.

I'm going on hiatus until next Sunday due to travel, but will resume testing then.

I'm also going to need to get a decent proper water loop for this machine. With the advent of the FX 8350, the time has come. Recommendations are welcomed.

On Windows 7, does it make sense to keep the two scheduler patches that were provided for Bulldozer on the Vishera's?

Hmmmm? How can I get this deal? Best I can see is $185 + tax. I'd like to get overclocking one of these bad boys too!!

Seeing a lot of this "Overclocked Memory" not making any difference coming up. On Bulldozer it did help with feeding the processor during high overclocks. But with the Optimizations of Piledriver it seems it can run max effeciency with only 1600Mhz Ram?

Anything faster is Bottlenecked? By Chip Latency?
So...maybe Slower Ram with tighter timings is the way to go for Piledriver.

Anyone find any reviews on Memory?
Would like to know speed differences and speed + overclock differences.

No matter what I'm getting an improvement from the x6 in idle power and multi-threaded encoding performance. I'm going to be happy.

xd_1771 orders an 8320....

Dude, any chance you'll remember to pm me a link of your results? I'm coming from a 1055T as well.

So jelly of your OC on your 1055T by the way. I need 1.5v to hit 4.0.

Need some more help plz!

In my research over which value board to buy for overclocking an 8320, I stumped into a couple questions, so if anyone can help me out id appreciate some answers!

1 - i was leaning on a rev 1.2 or 3.0 UD3 but I saw a few people saying that its VRM heatsink was insufficient for a heavily OCed 8xxx cpu and it might catch on fire O.o?
2 - does the UD5 have newer/better VRMs/power management than the UD3?
3 - does the UD5 have LLC? if so, which revisions? Giga's website only shows 1.x unlike the UD3 which shows 1.0, 1.1, 1.2 and 3.0..

basically, will I be safe trying to OC a 8320 upto 4.8 ~ 5.0Ghz with a UD3 or must i cough up the extra cash and get a UD5 or a sabertooth? =\ UD7 is definitely out of my budget

thx for this link, from here i can see that UD5 and UD7 use more efficient driver mosfets for the VRM than the UD3, but my other questions remain ^^

Does the UD5 have LLC now? if so, what revisions have it?
And can a UD3 safely handle a 8 core FX at 4.8 ~ 5Ghz for 24/7 even with the older VRM and smaller heatsink? :'(

Its around a 25$ difference between the two, so not exactly pocket change frown.gif
