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

I bought my UD5 off of Amazon with my FX 8350. It came with LLC. I think they have came with LLC for a long time. The people having problems are the people who bought gigas for their phenoms.

I like using OCCT and Prime. I use OCCT for about two hours to check stability and prime to check 24hr stabilty. I've found for me OCCT works quicker then prime in finding errors so it saves me some time while overclocking.

Whats the best way to test the psu. And I don't have a multimeter.

The best way is with a PSU tester. Cheapest is if you got an Harbor Freight or something near ya, their digital mulitmeters are only $3. I use one and it works well.

But for now you can try swapping out the PSU just to see if there's still a spike.

What software were you using to see the spike BTW?

Thanks this is a big change from overclocking Intel, so far Im impressed with the vishera line up.

So far for me, it just seems like no matter what is wrong it just hard locks. No BSODs. It's a lot more difficult, for sure.

Quick question, my first time using IBT, do I just run it on the "standard" setting? Oh btw received my 8350. biggrin.gif

Most will do 10 or 20 passes depending on cooling, air coolers will usually quickly hit max temps way before it gets near 10 passes, where water sometimes needs more time to saturate.

Yea I have one of those not to far away ill try to stop there in the next day or two. Im using HWmonitor. And I assume its accurate because the last time it happened the temps sky-rocketed (Running Prime). And in OCCT it would stop due to error.

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!!

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.

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.

That would not surprise me, it's been that way for AMD for a while now.

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

Uh.... what? since when?

All 990 Giga boards get LLC with Rev 1.1.

If you can afford it, people seem to be having good luck with Sabertooths.

So I can't really complain but if I had better CPU cooling I believe I could hit 4.8GHz no problem. I'm thermally limited at 4.7GHz currently but I run 4.6GHz because its 2 knotches less voltage and runs about 10 degrees cooler under load.

I didn't find that to be very true, but I do have the H100 blowing directly on it, so that helps.

Anyway, I thought about your problem, and I got a sneaky solution that actually doesn't look bad. If you have the room in the case to pull it off. A small 80mm fan.


Other alternatives include replacing the heatpad with heatpaste and really bolting the heatsink down.

would you mind telling me what revision number yours is, so I may try to ask around to see which shops carry a recent one biggrin.gif

thx, this is the kind of feedbacl i wanted but Im getting mixed opinions, over at the GA-990fx owners club someone tells me its just fine and the UD3 will take it like a champ.. frown.gif

decisions, decisions! more feedback appreciated!
