a64 3800+ x2

[nasrott]

Just picked one up from tigerdirect, runs nice 2.7 out of the box no voltage increase's.

code: LCB9E 0650RPMW

Is breathing some new life into a gigabyte k8nxp-sli, 2-36 gig raptors and 6600 gt's in sli. 512 pair of g skill. Am impressed so far... Payed $70 cad for cpu + shipping, cant go wrong if upping from a single cpu setup.

cant go wrong too if you can get it to 2.7Ghz

for a 70$ cpu its a GOOD DAMN DEAL

[nasrott]

ya cant wrong for the price, chip is fast compared to a single core set up that I had running, 3200+ @ 2.6.

From tigerdirect?

I just got a LCBQE 0649SPMW 3800+ from tigerdirect. Does 2.8 with stock voltage, 3.0 with close to 1.45, but because of my ram setup, I'm limited to 2.6 with acceptable ram speed.

Currently lowering voltage, seeing how low I can get it while still stable at 2.6.

[nasrott]

ya this one was from TD also, haven't tryed pushing the voltage yet. My G.skill loves overclocking so shouldn't be a barrier for me. Looks like mine is about a week newer than yours. 2006 week 50. My eyes are not so good anymore chnaces are mine is also a LCBQE NOT 9E as I posted farther up...

Hello Nasrott,
how do you know what to set the bios to when configuring the cpu? It asks for core speed multiplier and bus speed but how do you know what to enter?
I have read your settings in your post but where do you come up with these numbers? I bought the same cpu from tg, but am having difficulty getting it going.
Thanks for any help.

Is hardware dependent in a way and trial and error after that to get the best O/C your system can do. Your mem plays a key roll in your o/c you will get too also. Each system is different. Keep your HT clock ratio around 1000 and then continue raising the speed 200-210-220 you get the idea and test. Leave your mem on auto for now tweak later on once you have a stable system. not while trying to reach your system limit.

Hey nasrott, how did yours clock?

I got 2.8 GHz with 1.225 @ 110% = 1.3475 vcore. (cpu-z reads 1.296 v)
Memory on the 9/10 divider, running at 254 MHz.

That was prime stable for 24 hours, but 2.9 GHz is unstable even with vcore up to 1.45 on the 5/6 divider.

I'd expect an extra 0.1 volts to at least get me an extra 100 MHz from stock volts, so I'm not sure if the cpu just scales badly, or if I'm having trouble with my dividers.

[nasrott]

I haven't added any volts to it yet just playing on stock voltage for now, 2.7 was max on mine all the other higher try's wouldn't boot. Been lazy here lately. Will let ya know if some juice will increase it's speed.

I recently picked up this cpu from Tiger Direct also to give new life to my build. I got 2.7Ghz with stock voltage (1.35V) too. Anything higher didn't yeild much of a performance gain and the extra heat from adding more Vcore just isn't worth it. It runs at 34*C @ idle which is perfect and never goes above 48*C during gaming.
