Need Help OCing Sempron 3000+

post #1 of 12
Thread Starter 
Hello its been a while since I came back to these boards and I haven't got the nice computer I told ya guys about .

Anyways I checked guides on the forums for awhile now and I need to be sure about my RAM what do I do with its real confusing. And what about the Vcore and voltages on the CPU and RAM, Im not sure about the desicions. Everything is at stock settings right now.

My limits are only that the multiplier can go up to x5 and no higher its set and x4 right now I think. Any ideas on what to do to make sure the machine is stable, cause when I was OCing it one time the screen didnt show nothing after like 10 secs after boot but I wasnt sure that time. Oh and its a socket 754.

ARGH MATEY.

you're looking at the wrong multi. you're looking at the HT multi which controls your Hypertransport. You need to be looking at the CPU multi which should go all the way up to 9x.

lower your HT multi to 3x.

vcore is your CPU voltage and vdimm is your memory voltage. just use 2.7v on your memory, that should be fine. timings may need to be a bit looser on it. but also your CPU voltage needs to be adjusted only when your comp becomes unstable. max 1.7v, but i doubt you'll be able to even need that much. keep your temps low, around 45-50c, not over that or you'll have a nice bacon fryer. oh and good luck.

commander kool (i think thats his name) is, from what i've read, decent with sempron proc's. he has his 3100+ jacked up to like 2.6 or 2.7 GHz or somewhere along those lines. ask him for some advice with those things if you need it

you can easily hit 2.6, mine was at 2.6 with my old mobo, but my new one wont let me set my v core any higher than 1.55 .

set your setting as follows to hit 2.4 (stock cooling should be fine)

HT Multiplier - 3x
HTT - 267
CPU, Memory ratio - 2 -1.5 or 2-1.33
ram timmings 3-3-3-8 (2T)
V-core - 1.55

I promise this will work.

Is yours a Paris core?

Hey my I cant raise my FSB the limit is 250 I tried every way to increase it but thats all I got. I followed your instructions and my computer is very stable I ran Prime95 for 12 hours with no errors! My core is now at 2.2 GHz is thier any way to raise it without losing stability cause I can't raise FSB and HTT is at 3x the limit is 5x so...any ideas? And when should I raise it 1.7 vcore it seems like I dont need it at my speed.

It is best to only use the vcore necessary for stability, so the lower the better.
If your MB and CPU are a 1000 MHz base
4x HT for up to 250MHz
3x for 251-333

That didnt help either. Raising or lowering the multiplier isnt doing anything to raise the FSB. Is the motherboard locking it or something? Cause it stays only at a limit of 250. Any ideas?
