Ehh, I guess some of these Biostar motherboards don't like the 5000 BE as much as they could. Im running a TA770 A2+ and can get to 16x200 with the CPU crashing. It definitely wont pass a stress test. Volts set to 1.475 on the CPU. Running Corsair XMS2 4gb (TWIN2X4096-6400C5DHX) which is known to be decent with tighter timing at a slightly higher than 1.95v. I'm running it at 2.0v to make sure it's not the issue. I haven't tried the SB voltage yet and can't find a HT multi on this funky HT bios menu. It lists mhz.. 200-1ghz. They set the HT to exactly what I set it to.. 200 to 1ghz.. Doesn't do me much good.

From previous successful crowds of OC'ers, pushing the HT to 1200-1400 seemed to stablize many issue by the time these CPUs hit 3.2. Increasing RAM voltage helps as would loosening timing if your mem runs 2.1v+ or bottlenecks you sub-2v. Make sure your sticks can handle the voltage before you push them through it! At the moment, I just installed Fallout 3. I doubt 200mhz will make or break the game, but 200mhz may help me hold over for a new(er) CPU and mainboard!!
 
I've recently installed a 5000+ Brisbane in a new Asus M3A78-CM mobo and have set the multiplier to X15.5 in BIOS for a core speed of 3.1GHz and it is recognized by BIOS at that speed when rebooted. But, when in Windows, under full load, Everest indicates the CPU speed is topped out at 2.6GHz (so does CPU-Z).

I keep thinking that there is something simple I've missed in the BIOS settings. Could someone please give me a few pointers (I'm totally new to overclocking).

Thanks.
 
Are you using any of the ASUS utlities to change the BIOS settings when windows loads? I think there is a utility called AI Overdrive, or something similar, that I used to use. The utility might be overriding the BIOS settings when windows loads. In other words, during the boot the clock speed is set one way, but while Windows is running, the BIOS settings are temporarily modified.
 
keyter, I'm not sure why your voltage is so high, you may be able to lower it manually.
Heres my OC with a 5400 BE.

core speed: 3210.5
multiplier : x 13.5
bus speed : 237.8~458.6MHz=917
HT link : 1189.1
CL :4
tRCD :4
tRP :4
tRAS :11
CR :2T (the draw back of 4x1 g sticks)
running at 1.344 volts

1na dees days me'll figure uot sceene shotss.LOL



 
Primus, I don't have AI overdrive in my software package. One thing I did notice is that when I disable Cool 'n' Quiet in BIOS the computer will run in Windows at 3.1GHz (200MHz x 15.5), but ONLY at 3.1 which isn't great when I'm not working it. I did tinker with the speed of the FSB and have it running stable under load (with CnQ enabled) at 3.08GHz (237MHz x 13). Any higher than that and the system becomes unstable.

At the moment mine seems stable at 3150MHz, 1.475vcore. (15 X 210, I think). My RAM also runs at 450MHz now and HT Link is 1050MHz.

I just can't seem to get a stable 3.2GHz. If I lower the vcore below 1.450 it also compromises stability. How much will I need to "loosen" Ram timings to be able to overclock further?
Currently my OZC 1066 Reapers are at 5-5-5-15 (1/2T - I set it to Auto)
 
I can only get my AMD Athlon 64 X2 5000+ Black Edition to a 14.5 multiplier I have a M2N-SLI Deluxe MOBO,CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory(two kits) for 4 GB, and Thermaltake CL-P0075 80mm 2 Ball CPU Cooling Fan/Heatsink. How can i get it higher without it crashing
 
TCM, you may be able to go to the ASUS site and download AMD Overdrive.
It should be compatible with your board.

Keyter, I don't think loosening your timings on your memory will help?
There was something I read a while back about odd frequencies (ie...2.9MHz) messing the multiplier/divider ratios. You may want to go back to stock voltage, and if you can get to 222 on your FBS that should get you to 3.2. (fingers crossed, with no extra volts)


Skiscola, you may be able get to 15 with a little bump in voltage. Try adding .0125v to you V-Core. (it will propably default by adding .025v though, nobiggy) Be carefull if you've never done this before, type in the wrong numbers and OH $#!+ !!!! :-( spend more money .,.



Forgot to ask, what kind of volts are guys running on you memory?
 
Mine is at 2.1V, as rated by OCZ. I can bump it up to 2.4v, but I don't want to damage the hardware and void my warranty.
 
I just got a 5400 BE a few days ago and it was a breeze to OC it to 3.2GHz with a gigabyte GA-MA69G-S3H. Using a x16 multiplier all I had to do was bring the vcore up to 1.375v from the stock 1.325v to stabilize the OC.

Mobo must be the issue. I've never used biostar boards so I have no idea the OCing potential or issues with them.

 
Abit Fatal1ty AN9-32X
2GB OCZ Dual Channel Gold Rev 2
AMD X2 5000+ BE
Stock cooler
Radeon 3850 512MB

all i did was up the multi to X16 and left everything at stock....at multi x16 the divider is at CPU/8 making ram run at 400MHZ (800MHZ)...........even C&Q is enabled and its purring along just fine. temps range from 19C to 55C.....how accurate i dunno till i upgrade the cooler

Godsizesnakeyes, don't know much about Gigabyte boards but needing to bump the voltage on your vcore could also have something to do with the CPU also. As long as you have good temps no biggy though. You may be able to raise your FSB and sqeeze a few more MHz out of er.
What memory you using?

Ricman, thats a pretty decent OC. I've read where the 5000 seem to be a little better clockers in the AMD family. You probably won't get much more by raising the FSB (but you never know). You may give it a try after you get your new cooler. Those OC Gold's should be able to take some tighter timings even if their 800's. I've got the 8500 Reapers (1066) running at 917 MHz with 4-4-4-8 timings on 2.0v
Stock timings are 5-5-5-15 2.1v
 



I've been using 4x1GB of Transcend AxeRAM DDR2-800 since I built my rig 1 year ago.

It's turned out to be great ram with good reviews so it's a shame it seems to have been discontinued by the manufacturer.

I'm working on a new custom case with even better airflow and then I will try to get some more out of my 5400 BE by playing with the FSB. I've had my FSB up to 270 stable when I was using a 4000 brisbane OCed to 2.8GHz but it took alot of tweaking and alot of juice. So I think with my setup a 5400 BE @ 3.4GHz is realistic with proper cooling.
 
I could boot and load windows at 3.450 but as soon as I moved the mouse it would blue screen. that was at 1.40 volts. At 3.376 could run apps, but wasn't stable. Don't want to throw to many volts at er' yet. Don't want to spend any money till see what the new phenom II's are made of.
 
Hey guys

Any chance the AM2+ phenoms etc will work in my AM2 Biostar mobo. Biostar TF570 Sli. Has anyone even tried?
 
heh I have a 5000be and I can't can't mine to run at 3.2 and I spent about a week playing with it. In the stress tests I run it seems the core#0 fails after about a minute though core#1 is able to continue. This is with ram v up and vcore set to 1.425 it only wants to run at about 3.1 stable. I run at 3.1 on stock voltage.
 
I get my 5000+ BE @ 3.2GHz on an MSI K9A2 CF-F mobo without any adjustment other than taking the multiplier to x16. I'm using a ZEROTherm BTF80 HS/Fan (w/ included thermal paste) and temps stay in the 40-45C range even under full load.

I think what some of you are forgetting is the fact that BE chips simply have their multipliers unlocked. Tinker around with the multiplier, not your FSB. Once you find a stable multiplier, then go ahead and try raising the FSB a little at a time.
 
Got my 5000+BE to 3.2Ghz easily stable with X13 multiplier 1.392V, just upped bus speed....RAM running @ 940Mhz 1.9V HT link @1200, but easily brought below 1000 w/800 multiplier.

Had this 5000+BE past 3.3Ghz, but started getting intermittent errors during stress testing..

Right now this rig is running perfect...hours of any game NP! decent temps.

Ill post some screenshots soon.
 
I'm pretty sure that it's my mobo that is holding me back since I built this system as a budget rig and it uses n520 chipset lol though on the bright side i only paid $30 for it at the time.
 
This took a week of playing! For some reason it does not show the multi or vcore but they were 16x 213FSB 1.52 vcore. verified and stable but i dont want to push it so i stick to 3.2 This was done on my ASUS M2n32 WS PRO
his
Lost the original and had to use a screenshot of my desktop. by the way i hit 3.5 but it was not stable so it didn't count. And this is on air cooling Phenom cooler lol.
