Solved Replacing CPU on Socket 754

Hello, all, and here I am once again.

My question this time is about replacing an AMD socket 754 CPU. I made a post earlier about my Sempron 3000+, and once I started digging around I'm thinking about replacing it, since equivalent chips are really cheap (~$10).

First I was looking at the Sempron 3400+, but then I realized some of the Athlon 64 chips are socket 754's too, and they have double the L2 cache. That's really important, as I'm looking at this for a future personal server machine.

Really, my question is: The Athlons have a HT speed of 1600, and my current HT on the 3000+ is 800; is this dependent on the mobo, or is it CPU bound? I assume that I can just pop this sucker in, do the thermal paste and use it? Heat's not an issue; I rarely if ever hit 48°C on the current Sempron. That, and am I correct in assuming that this needs the 'middle dot' method for the paste?

Current specs:
CPU: Sempron 3000+, 32K L1 128K L2
Mobo: Asus K8V-MX/S (Fujitsu-Siemens D1711)
1024Mb of DDR400 RAM
Integrated graphics (irrelevant and adding a video card soon)
PSU: ISO-400 300W power supply (might need 400W replacement?)

EDIT: Before you say it, I am going to get a 2Gb set of RAM for this thing. 1Gb is barely cutting it. ;-)

✔ Best Answer
The S754 was my favorite platform back in the day. Your current Sempron is one of the "bad" ones because it only has 128k L2. The "good" Semprons had 256k. The Athlons have either 512k or 1MB. There are several different cores (Clawhammer, NewCastle, Venice) with different voltage requirements & different wattage ratings so make sure you get one that's compatible with your motherboard. Middle dot method is correct.

The HT bus isn't a problem. 800MHz & 1600MHz are the same thing. It's similiar to the way DDR RAM can be called by it's frequency or it's DDR rating. For example, DDR400 RAM can be called 400MHz (DDR rating) or 200MHz (frequency).

Ahhh. So basically, as long as the Vcore stays the same and and the TDP is similar, all the socket 754's are interchangeable.

The one I'm looking at on Amazon appears to be a "Venice" core, with a 59W TDP and a Vcore of 1.4. Almost exactly what I have right now. So I should be good, ordering right now :D

Just look for a 3200+ with at least 512 or more L2 there the best bang for your buck. I have 2 of them lying around here and one still chugging away in my garage pc.

Compaq Presario SR2010NX
Athlon X2 6000+ 3.0Ghz
4GB DDR2 800
nVidia 512mb video
Segate 500 gig sata
NEC ND-3500AG DVD R/RW
Linux Mint 14 Cinnamon

One I'm ordering is a 3200+ with 512K. The only thing they seemed to have on Amazon... at any rate it's shipping now, I'll post back when I have it installed :-D

The Athlon arrived today. Installed it, and it works great! So far I've noticed a ~25% performance boost, it shaved about 5 seconds off my boot time and reapplying the thermal compounds actually dropped my core temperatures 3°F!
