3.0GHz Sempron 2800


Recommended Posts

Well, I'm not there yet, but I think I can do it. Following this review of the lost circuits I have decided to go Vista in the hope that my temps would decrease and what do you know, they did.

 

Briefly my current OC:

 

- HTT 337, CPUx 8X thus 2.7GHz on stock cooling + AS5

 

- Voltages: CPU 1.5V, ram 2.0V, the rest on stock

 

- HTx 3x, DDR 1:1 ratio

 

I'm at 34°idle and 48°Burn after 7 hours of prime. What do you think? I'm already @ a 68% OC but those 3GHz are so close... and I don't think I've reached the limits of the stock air cooling.

 

Would additional CPU cooling help? I'm thinking of a Big Typhoon or a Tuniq tower, but these cost more than the CPU itself.

I am deeply hurt :P

 

It's true that is has only a quarter of the L2 cache of the A64, but does it really matter? If it can reach 3.0GHz I bet it is just as good as a 2.8GHz A64.

 

My friend, the aim is having a 3.0GHz K8 for 40$, that's OCing.

 

*EDIT I thought of removing the IHS. How much better do you guys think it would be?

Whats the point of getting 3GHz out of a Sempron? An A64 3200+ at 2.6Ghz would wipe the floor with it. The AMD Sempron is just an Intel Celeron equivalent.

 

Huh? what's the point? what?

 

 

Overclocking is the point.... :cool:

 

Taking a Sempron to 3G's just for the sake of taking it to 3G's is the point. And with an 8x multi to boot...

 

It's not just about performance... Its about OCing the crap out of a chip to see what it can do. :nod:

 

 

 

@ dragosmp

 

Have you taken the board up to 375 HTT to see if it is stable there?

 

Before I would pop the lid, if you even can (aren't the AM2's using solder instead of paste now, I thought I read that somewhere. Maybe I am imagining it...) I would get a Heavy-Duty-Super-Duper-Fancy-Go-Faster Air Cooler for that chip. If your load temps are 48c on the stock HSF, I'll bet you could drop your temp by ~10c. Those stock HSF's are terrible...

 

Something like a TT BigTyphoon or Turniq Tower would help you get closer to 3G's provided your board can handle the higher HTT. I think those coolers cost ~$50 & they are worth it. Just remember that you can use them on the next CPU you buy & if it is a dual core that you want to OC the crap out of, you will NEED the extra cooling. ~$50 for one of those HSF's is a good investment in my opinion...

As far as I could find on the web this mobo should be stable up to 440HTT, not to mention I've upgraded the NB cooling. My CPU has its multi locked and doesn't support C n' Q as it has only 1.6GHz stock frequency.

My future CPU would be a DC, probably a 4000 x2 65nm but with the next revision, the current 65nm have left me with a bitter taste in regards to OCing. A good air cooler is a MUST, you're right here and this time I'll go for the best.

 

BTW, which is the best? There are some options, the BT, Tuniq, VF9700Cu... I'm not so sure what to choose.

Tuniq is the better performer just make sure you got the room for it.

 

There is just one more problem with the Tuniq: it lacks support for the AM2. On the official site it's said that the cooler can be mounted on AM2 with the help of the Zalman ZM-OC1 clip which is nowhere to be found (at least in France).

 

Is there any other way to mount it on a AM2? Maybe some of you have seen this issue and solved it in a way or another.

 

Mean while I found quite an offer for the Scythe Ninja rev B: 40€ (aka 40$). What do you say about this one? I would prefer the tuniq if there was a possibility of mounting it on my mobo.

Thanks dr bowtie for the thoughts, I really hope this CPU can do it.

 

10x to you too phoetus, that's a compelling review and I think I'm going to get the BT. I tried some tricks on my CPU today and it kinda refused to boot at 2.8 GHz. I've read that a guy that had S2800 managed to get it validated @3.06GHz but as for stability it was stable only @2.7GHz which is where I'm at right now. The thing is he needed 1.65 Vcore, a lot more than my stock cooler can take.

 

For the record: the Tuniq can be mounted on AM2 only with the Zalman ZM-OC1 clip. It's not sold separately, the clip is an accessory for the ZM 9700CU, so no tuniq for AM2, at least for now.

Good job on the O/C!

 

I had a lot of fun with my 754 Sempy's a year ago. They can O/C like crazy, and if you blow it up, it's not the "end of the world"!

*all in my opinion*

the point is that this poster has done something he is quite proud of, and honestly is something worthy of being mentioned. People like you who crash in on a thread banging about how it sucks is pretty damn rude.

 

If you aren't impressed by it, don't post here because one of us will see it and rank you out for being a jerk.

 

 

 

 

dragos: don't worry about guys like this. I'm more than impressed with it as I've got some Semprons around between me and the mods and they all overclock very well and they all are excellent budget cpu's that are strong when overclocked.

 

Good job on it.
