Unofficial Athlon X2 4850e Overclocking thread

[KTE]

Trying to keep 0xC0010064 as the COF would work much better I think, that's where my multis are coming from always.

[VVJ]

Here is a snapshot for low-power Opteron 2204 45W processor.



An Athlon 4850e even looks much better!

does anyone have more overclocking results on this chip?

Aqui vai o meu.
Here's mine.
Stock voltage.

[Kardahs]

Hi All,

Just got mine a few days ago and I'm testing step by step, for the moment I tested lowest voltage at 1000Mhz (stock idle frequency) and went down to 0.850V, I think it won't go far beyond that but I'll try. I'll try to post other results when the tests are done

@ NOOB : I see your CPU-Z screenshot shows some overvolting compared to stock voltage (1.296 instead of 1.25), I have the exact same overvoltage shown in CPU-Z with my Gigabyte GA-MA78G-DSH3, do you have an idea where it would come from

Bye !

I'm using a g1 brisbane @ 1ghz 0.80v for six months now...
I never tested the stability on any burn test, but it is 100% stable at Idle, and I even played "NFS porsche 2000" at this clock and voltage for hours, anyway, what would be the estimated TDP at such clocks/voltages!?

[Kardahs]

I don't know what would be the TDP at that speed and voltage, I'm monitoring only the total power consumption of the PC.

Seems I didn't get the best sample, I'm getting errors at 2875Mhz (12.5 x 230Mhz) at stock voltage, 2750Mhz went fine but not here. Have to do more checks but I already lowered the HT Link speed and still get the same errors, I'll try cooling actively the CPU, it might help a little bit.....

What is your cpu cooling and what is your board?

[Kardahs]

What is your cpu cooling and what is your board?

My board is a Gigabyte GA-MA78G-DSH3 and the CPU cooler is a Cooler Master Z600. I use it fanless (with no fan attached to it), however it benefits from the extraction fan of the PSU located just above.

This evening I added a little bit juice (1.275 in BIOS instead of 1.25V) and 2875Mhz went OK

How do you get that? I can only get to 3ghz with 250fsb 12.5x and 1.425v

[Kardahs]

That's a matter of luck

I achieved the 3ghz with mine at 1.325 VBIOS? Now running it at 2750Mhz on stock voltage

[arthur92710]

What if he burned it in?
I did not so that might be the solution.

[N00B]

mine was just out of the box!
I'll try to get to 3.6Ghz

[arthur92710]

no way man!
lucky!!

I think its the ram.
What I have is nothing compared to yours!

Well I can go and start the "unofficial Athlon 4850e Underclocking thread"
Check out my low underclocks!
Low and
Low but higher multiplyer They both draw .80A Idle

[VVJ]

arthur92710,
Ha-ha, 90MHz for the reference clock?! LOL! Is it really possible?

[justapost]

no way man!

Impressive ref HT. Lowest I could reach was ~165MHz on the DFI790FX. What mobo are you using?
How low can you go with the cpu voltage? I'd expect 0.7-0.8V here.

Damn!!

Was that stable??

My mobo is the ASUS M3A
I set the FSB to 600 and multi to 5x voltage was auto.
Then in windows I used a64clk to test other multipliers.
YES!! I win in something!

So it's actualy a bug in the bios allowing such an low ref HT?
Bios 600MHz -> System 90MHz?

[arthur92710]

Must be a bug.
Well I was able to get to 3ghz.

nice cpu

[Kain665]

Here is mine. 10hrs orthos stable. It could run fine at 1.33v, its just this Gigabyte 790x DS4 either overvolts or undervolts :x

Nice.
I just tried that but windows keeps crashing when I run prime95
humm I wounder what you keep in your "stuff" folder

what kind of temps are u guys getting. Im getting weird temps with my 4850e, I have it cooled with a ninja mini (as5). Thing is, its (core 1/2) idling at 15-20´C (at start, usually 20-25'C after its been on for a while), but when I put prime95 small ffts on it makes a huge jump to 50-55'C (core1/2). vcore is set at 1.15v in bios, stock speeds.

I mainly use everest ultimate for temp readings but I also have hwmonitor. Both give the same temp for the individual cores but HW states TMPIN0 as 70'C+ when having small ffts on, confusing.

I first had a gigabyte 780G matx board but after a bad @bios flash (kickin myself of using that) I got a 690G asus board as a temp. recplacement. I get the same temps with both of the boards.
