Return of a Legend - no, not me: AMD FX-8300, 95W TDP 8 core awesomeness :D

[FlanK3r]

I have better around 2600-2700 than with 2200 .

[EnJoY]

Welcome back Oliver, nice to see you again. =) I don't come around much anymore myself, but very nice results with AMD on air.

[Fr3ak]

Sorry for double post but i just flashed back to bios 1002, same thing. Still no 300 FSB. EZ flash lets me flash back without having a moan about an outdated bios, good thing Asus!

I will give it a try, most likely today. I have not been around at the weekend (as you might have noticed, sorry).

Look who is also still here. Unfortunately and to be fair, I have to call it water cooling which uses air, but still, it's way better than just plain air cooling. I wanted to text you the other day, but had to run - will do in a bit, so be scared xD

The AMD section has been dead all weekend, i wonder where all AMD enthusiasts have gone.

This FSB thing is driving me nuts. Tried bios 1002, 1101 and 1201, all were the same. Tried booting at 270, with ram, ht link and cpu-nb all turned down low and tried to raise FSB in windows with TurboEVO but it gave me a BSOD when i wanted to press apply at 280.

Curious to see if your board can do high FSB.

[The Stilt]

Cannot quite figure out why you want to raise the BCLK in first place, however C5FZ is good up to 340MHz++ BCLK.

[Zeus]

Cheers The Stilt.

No idea why i want that myself but i guess i was exploring the limits of the board. Up till now my last 3 Crosshair boards all went 300+ except for this one, maybe that's what's bothering me. At post it makes it till the VGA debug LED together with Q code C5 and then it starts over again.

Just wondering why.

[FlanK3r]

ht voltage? PCIe clock?

[Fr3ak]

The Stilt beat me to it

Quick test with 24/7 voltages in 5MHz steps, booted with 270MHz:


I hit 320MHz, 325 crashed, at room temp without tweaking, so I am sure I could get more out of it, if ever needed...

My volts:
VCore: 1.4V
CPU HT NB: 1.275V
VMem: 1.65V
NB voltage: 1.225V
NB HT voltage: 1.3V
Other settings on "auto"
BIOS 1201
PCIe: 110MHz

We can be happy, Stilt dont fight with us in Cinebench R11.5 . His cold air could be winner . We had awesome cold at Firday, -17.5C outside, but unfornately, I was sick. Cant open window for my health condition

An awesome paper launch from AMD.... again.

[I.nfraR.ed]

Zeus, did you try loosening trfc? Also, do you try with both cards running?
I had to change trfc from 110ns to 300ns on my C4F in order to boot past 275+. Got it to 345, but it freezes just before it hides Welcome screen of Windows 7.
This HD7850 is very picky when we're talking about pci-e clock, so it might be part of the problem.
Didn't play much with it, but will do when I have some free time.

The word enthusiast has been replaced by fanboy. They might all be in hiding to not get trolled upon.

Ivan my friend...i owe you a big beer!



300ns did the trick! I would have never ever looked into that myself, thinking trfc is a completey memory related setting. I guess not.

Just tried 320 with no changes to any voltage whatsoever and it booted straight into Windows. To see if it was stable i ran 10 passes of IBT and it completed without errors.

No need to see what i can achieve here, it's just that i couldn't get it over 270 that made me wonder.

Thanks everyone for helping. Guess i unintentionally found a way of derailing your thread after all Oliver.

[aussie-revhead]

Guys, can anyone reveal a physics score in 3D11? Im curious to see how these go, shame its being launched in the shadow of haswell .... good luck to AMD on this one....

[I.nfraR.ed]

This is one of the keys for high HTRef with e.g. Sempron on DDR3 motherboards.
Some boards reach 350MHz with tight/normal timings, but past that need fiddling with trfc and memory/IMC related settings.
Did 452MHz with Thuban on M4A89GTD this way.
So that was the first thing I tried and it worked. Anyway, you don't need it for unlocked chip, but is very valuable for low-multi locked chips on LN2

Appologies to Oliver from me too.

Physics Score
8203

Thats at 4314Mhz, with probably not the best timings/efficiency.Physics score is good on vishera, game tests however are not.

[Fr3ak]

hehe Zeus, I was about to mention it, but that is totally fine by me. Nice, you figured it out

Reminded me of this "gem": http://www.xtremesystems.org/forums/...and-417-MHz-HT

Ah well, thats a bummer but thanks for the info.

Hardware enthusiasts want hardware that performs at enthusiast levels. AMD fell behind for too long, it's hard to get excited about parts that reviews all over the web are showing have real issues with gaming.

They basically ran out of "I'll buy this to support competition while the other people get better CPUs".

wow, TRFC and higher BCLK...Its new for me too . How is it possible exactly?

[Fr3ak]

I have new memory on the way, so fingers crossed it will clock well on AMD without having to solder on a Intel IMC, haha

My multimeter should be here by tomorrow, so I can finally doublecheck voltages and while I am at it, I will swap PSUs just to make sure my current one is not limiting me for whatever reason. Well, then, there is basically nothing left to do for me after I found the limit of the memory and the rest of the 123 settings, so I can go subzero in order to make a huge fireball out of the carefully collected components

is worth to try Hyperx Predator 2400 modules with FX-83XX processosrs ? I cannot found any tests using this memory in AMD processors.

They are with Hynix CFR (4GB modules) or MFR (8GB modules).
Work like a treat.

[zhadoom]

Thanks for the info.

[Oese]

Maybe other programs running. I use real-time setting for cinebench in applications/processes. You wont see the progress and may think program has locked up but its not and scores are more consistent and of course higher
