[OFFICIAL] FX-8320/FX-8350 Vishera Owners Club - Page 671

post #6701 of 67020
hey everyone, kinda new to this overclocking business, kinda addicting but pretty frustrating at the same time lol. I just built my self a new gaming rig was well over due. I keep seeing everyone getting the great overclocks with there 8350's and im having trouble just getting it over stock settings. my system is as follows.

fx8350 w/h100i push/pull config
asus m5a99fx pro rev2 {bios is recent}
16gb gskill sniper 9-9-9-24 1.25v
2x7870's
750w xfx psu silver rated

all power saving features off llc is set to vhigh.

if anyone can give me a little insight that would be amazing or atleast where to start.

Good job Wolvers.. Do you have your NB, HT, and Dram linked. I have noticed that stabilizes the overclocks and allowed me to go further on lower voltage also. It seems the stress added by going higher with clocks when overclocking puts more work on the internals to get the different buses linked or synchronized when they aren't. By linking as much as possible it seems to relieve that somewhat. At least for me it did. I have very low voltage on everything on the board, even though much of it is running very high but in sync.

They're not linked actually, I think they're about ~2200NB and ~2400HT. I will try with NB at 2400 too though, especially if you think it will help with stability at lower voltages.

re your comment about CnQ not working. I noticed that when I was at 302 bus clock. That may be a factor, higher bus frequencies.

Yes, link HT and NB at around 2400-2500

Actually, I think ga1ve1an was talking about linking the RAM speed too which means I would have to see if my RAM will do 2400Mhz. I'd have to back off the timings but it might do it, I've seen plenty of people get the 30nm Samsung RAM happily running at 2400Mhz.

I'll try just NB and HT synced for an opening gambit.

Is this a typo? 1.25v? Probably suppose to be 1.65v? Just checking.

I have the same board, you could start with 4.5Ghz
- CPU Voltage 1.35v (FSB 200, Multi 22.5)
- LLC Ultra High
- Turbo Disabled
- Disable Power Saving Features (APM, CnQ, etc)
- Change the Voltage settings from Offset to Manual Mode.

Everything else should be ok on Auto. If it's not stable while stressing (10 Runs IBT on High) Then increase the CPU Voltage a couple notches and retry.

My sammys will do 2400, but I have to use 1.5v+ with 11-11-11-28 2T timings.

I formatted, reinstalled win7, and used that exact link. I only get 47 GFLOPs @ 5.3GHz.

I have never considered what you have posted above.
Will put this into action the next time I hit a brick wall.
A new FX-8350 has arrived this morning
batch nos: 1244
Time to reset bios and see if this one is any better.
With a quick test I did seems to be very similar to the 1240 I already have.
Not looking good, this will be three CPU's that dont clock well on this Crosshair V .....

Hey thanks.. Regarding your CPU you might want to read this thread ComputerRestore started.

http://www.overclock.net/t/1334836/amd-piledriver-individual-core-module-errors-discussion-thread-stability-issues-stock-and-overclocked

Some modules are just not good and block the rest from going higher unless you disable it. You might have got one of the CPUs that have a module that isn't that good. I think 1244 batch numbers were spoken about in there with the 1240's possible being the worst that don't overclock that well with all four modules. If you can find the bad module and disable it you should be able to get to 4.8 - 4.9 on the others from what I read to verify this.

Do what Computerrestore mentions and then once you find stability start increasing your fsb and lowering your multi to maintain as close to those stable settings as possible. Then you can see if with the lower multi you can go higher on the cpu. If possible try to keep your NB,HT, MEM in sync if possible or as close to together as possible.

You could also try anything in between 2200 - 2400 if your memory is not so comfortable at 2400. If syncing allows you to get an extra 100 or so MHz overclock that would be more performance than going with a higher bus. I would say syncing is what would be important even if it is at a lower bus.

Yes linking all three seemed to be what relieved most system stress(by this I mean having to move voltage up much more on other components ex. CPU/NB, Memory, and of course the CPU for stability). Synced the stuff just seemed to mesh together without all the extra voltage and then I just had to focus on CPU and the voltage I added to the CPU was for overclocking not to help stabilize other things.

Hi!

Yes, ive read that thread, lots of good info

The 1240 seems to have hit a wall at 4800mhz for prime95 stability across all modules, but I need to try your high fsb technique on it!

Currently playing with the 1244, its currently priming at 306x16, jumping around the 4900mhz mark with 1.475v set in bios, package temp at the moment is at 43C but its not run been running long.

Have completed IBT run, set at custom 6000mb, same settings but with 1.43125v, higher CPU/NB/HTT then the current prime session



Crap prime95 failed, time to up the voltage to 1.48125v rolleyes.gif
