Question about pci & agp locks with oc'ing

[Jpark]

I'm wanting to overclock my sempron 2800 a64 to around 2.2ghz. My question is, should I worry about a mobo not having locks on the pci and agp with only going this high of oc?

Yes, very much so. The lack of PCI and AGP locks really limit what overclock you can acheive.

I'm not looking to heavily overclock, just something mild to boost performance.

do you have a sata or ide hard drive?

I have both, but I use sata for my primary drive and an ide as an external drive

If you don't have working AGP/PCI locks, then you will have trouble OCing. However, most newer motherboards have working locks, so you're probably ok. What motherboard do you have? Maybe someone can tell you if that motherboard has working locks or not.

YES!!!!!

Most new boards now have them locked by default, but its good practice to make sure before even trying to OC.

I currently have an msi k8mm-v and it has no oc'ing ability. I have a qpack case and the only thing it accepts is m-atx, so I'm limited to that. I was thinking about getting the soltek below, but after some research I don't believe it has any locks.

Sounds like I'm SOL

I dunno if you're SOL just yet. Requiring M-ATX definitely is a problem...but this ASRock and another Biostar use the Nforce 410 chipset which *should* have pci/agp locks. It's based of the NF4 platform....but has integrated video. I don't know if that's the direction you're looking to go...but it's an idea.

Edit: Oops looks like the 410 is the southbridge...it's really a 6100 IGP chipset. Still looks to have some promise. Although, I still am not 100% sure that it has the locks. Might want to check around.

Unfortunately, it seems like that chipset is NOT locked: http://www.via.com.tw/en/products/chipsets/k8-series/comparison_k8-series.jsp
Where it says bus architecture, Asynchronous means locked, and the K8M800 chipset is not asynchronous. Sorry, but you are SOL

Good lines!!!:

Anandtech reviewed that chipset recently: Link
Those DO have working locks, so you should be good if you use a board with that chipset. Good find CharlosCarlies!
Edit: Those are PCI-Express, but it has decent on-board video, which could hold you over if you don't have/aren't getting a PCI-Express graphics card
