Trouble OCing my 5000+ BE with a Gigabyte M57SLI-S4

I put my machine together a few months ago and finally decided to overclock it. I read up on what the 5000+ BE can do, and started inching my way toward it. From what I hear, the standard stable point is 16X multiplier with 1.4V. It started creating massive amounts of errors in Prime95 at 15.5X and 1.375V and doesn't even boot at 16X/1.4V. It's reasonably stable (running extended Prime95 test, no errors so far) at 15X/1.35V (CPU-Z shows it at 1.375V) and running at 3015 MHz. I am admittedly an overclocking newbie, and would appreciate any help! Thanks in advance.

I bought the 5000+BE because of its easy/effective overclocking. I'm just wondering why I can't reach the standard benchmarks with the same settings - unless I have to, I'd rather not deal with HTT multipliers and the FSB. Thanks though.

I'm not doubting the validity of your advice iluvgillgill, only saying that others overclocking the same cpu didn't need to adjust those settings to reach 3.2 GHz @ 16x/1.4V - I'm looking for tips on what maybe different about my mobo or reasons why I'm unable to do the same.

come on crlaozwyn!im not saying what i said is 100% correct to your case.BUT if someone can do it on XXX setting doesnt mean you can do the same.even if majority can do it it dont mean you can do it as well because you might be the unlucky one.

but in this case hope someone else will hope you.im off.

Crlaozwyn, multiply the cpu to 15.5 @ 3.11ghz, leave your mem and volts on auto. I have the same proc as well.

The reason is that you loose performance on your memory from 800mhz to 776mhz (down to 667mhz) when you go past 3.1ghz.

It shows on mine but then again I have the Asus M2N32 SLI Deluxe WiFi. Could be the Ram( don't quote me on that).




iluvgillgill said quote",lower the HTT multiplier and up the FSB is a better way of getting more performance out of amd system. ( UH sorry to rant on you but that's totally wrong my friend) You need the HTT at max to get the best of any AMD processor. It also depends on the MOBO your using as well too. It has to support the HTT what the proc can handle as well.

Good Luck too you Crlaozwyn.

alright. but what i been told in other amd thread is that the higher you set the htt multiplier you will have lower fsb on the cpu even at same speed. and memory will link directly to the htt. can you show me some benchmark to prove your point?

i think you are getting it wrong here.you get the max out of CPU but not the memory.

I get a whole lot of error on prime at 3.2 GHz but in the end, it's still stable during games and all so I don't raelly care about that test. It,s not like I ave critical things running on my computer so if it crash well then too bad my game will free and I will have to reboot.

You should not have to reduce the HTT multiplier since it doesn't get modified by just upping the CPU multiplier. People that overclock non BE processor need to increase the system bus so the multiplier generate higher total clock speed but it seem that an HTT higher that 1 ghz (200 mhz bus x 5) gets unstable. Mobo limitation probably.

That's where I'd be betting. Or it could greatly depend on temperatures and what cooling solution is used with the 5000+ BE. If you're using a lowly Masscool or something it's no wonder you can reach the same clocks as review sites that use the TRUE, S1283 or Ninja. Let us know your WHOLE setup, and that'll help us answer your quesiton/problem.

Edit: It could also be a memory overclocking issue, since AMD processor base the memory frequency off the CPU clock, not the system reference clock. Set your memory divisor to 8 or 9 (@ 3.2Ghz - DDR2 800 or DDR2 711, respectively) and increase your CPU multiplier to 15, 15.5, 16, etc.

Also, check your BIOS date and if there are any more recent revisions on Gigabyte's website.

I have the same mobo and proc combo as you and I can't get it past 3 ghz @ stock volts either. I've tried adjusting just the multiplier, the multiplier and the cpu clock, and just the clock, using anywhere from 1.35 to 1.5 volts, but still can't get past 3. However, I owned a 4000+ before this BE and I'll tell you the mobo freaked if i adjusted cpu voltage. I did get it up to 2.8 ghz for a bit but it wasn't very stable, 2.625 seemed to be what that 4000+ could do. OC'ing doesn't appear to be the M57SLI-S4's strength, at least not the Rev 2.0 boards that are out now. But yeah, I wanted more from the 5000+ BE, I would of bought 6000+ if I knew that 3 ghz was the max.

And yes, OC'ing this processor should not be motherboard limited. However, considering the lack of results that myself and others have reported using this model, there's little else to blame. BTW, I have a Cooler Master Hyper TX-2 slapped on it (only because it was recommended by this site). Still stuck at 3 ghz.

Alright, full system specs:
Antec 900 Case
Rosewill 550w PSU (I know some people don't like Rosewill. It's what I could afford)
2xG.Skill 1Gig PC2 6400 800MHz @5.5.5.15
Gigabyte M57SLI-S4 Mobo
AMD 5000+ Black Edition with Zalman 9500
EVGA Geforce 8800GT SSC
2xSeagate 500GB drives @ 7200 RPM

It does run stable at 15X multiplier and 1.35V. Gonna see if I can't upgrade bios.

I also have the same problem. My 5000+BE can't go above 3GHz without instability or not booting at all. I even have to set my voltage to 1.375 to get it stable at 3GHz. I have pretty much the same board as you, except mine is the SLI-S5 which is almost the same, but with some extra features. I guess this particular generation of Gigabyte boards can't overclock well. If you do finally manage to get to 3.2GHz, please let the rest of us know how. Otherwise, all I can suggest is let your system run at 3GHz and not worry about wringing out the last 200MHz. I am kinda disappointed too, though. I really hoped that I could get to 3.2 when I bought the Black Edition.

i think that iluvgillgill could be right about lowering the htt at higher fsb. when i overclock my phenom 9500 from 2.2ghz to 2.7ghz, i can do it on fsb alone. but if i want to increase the clock speed even futher i need to decrease the htt multiplier in order for the system to be higher at any higher speeds. the next thing that limits my ocing is the ram. as i insrease the fsb, the ram speed goes up, so i constantly need to erither change the ratio, loosen timings or increase voltage for system to be stable. 2.8ghz is the most i've ever been able to get with my 9500 phenom. that is 600 mhz right there. seems weird that your unlocked 5000be can only do 600mhz as well, considering the fact that phenoms are supposedly the worst overclockers.

and once you start lowering the htt multiplier, the processor performs slower. way back when i first build my computer, i wanted to see how my cpu performance affected some benchmarks, mainly the 3dmark06 scores. i found out the lower the htt mulitiplier is, the worse the performance. in the end, i noticed that the score began to go down after like 2.65ghz. and there could be have been only one reason, lower htt speed due to lower htt muliti.

Thank you very much godless. oh!

A lot of mobo's have problem OC'ing these CPU's. The cant deliver enough juice simply put. Just that they can run the cpu doesent mean they can oc it. If the mobo can handle the bigger phenoms then it cant oc the 5000bc.
