I was wondering how successful overclocking with a P4S8X was....

[Mickey21]

How successful have you or anyone you know been with overclocking in the Asus P4S8X SIS648 motherboard. I have one on the way, but just wanted to get a feel for what everyone was seeing in the quality of this board. I have seen mixed reviews on the whole SIS648 based boards, but not much besides one review on the Asus, and it was pre-release rev, so just wanted to check on how a released version was doing. Any help would be much appreciated. Thank you... I intend on sticking a 1.8A in it if anyone has any specific details on that one....

Forget about OC bro.asus p4s8x hasn't got agp/pci lock.fsb150 max take a look at the review done by CPU 3D.com and OCworkbench news.

The recent 1.8A chips are good to at least 2.6 most hitting 2.8, ive had three in the last week all packed in August that hit 2.82 on air,so the SIS648 is definately not the way to go, also its rumoured that SIS are already hard at work with a anew revision (remember the DX) and that Abit have stopped production of the SR8x.The best DDR board right now is either a Abit BD72 which with Corsair 3200 or good samsung can easily do 160 fsb with 3/4 setting = DDR 430 ish, high bandwidth, low latency and rock solid.Not more expensive either.But most of the 845E boards are solid, but for oveclocking choose either Abit, Albatron(good reports, will be testing next week) or Asus(lack of 3/4 above 132 is a minus ).The BD72 is the performance/value option though for definate, whatever you do stay away from E---x for the P4.

I was wondering about that, because the MSI has an AGP/PCI multiplier lock, and I know that the SIS 648 chipset supports the lock. Is it possible that ASUS will add that capability in a BIOS update?

Thanks for the help BiosMaster. I am going to check out those options, my motherboard choice is not set in stone. I thought the P4S8X might be a good choice, but I am going to do a little more checking out. I was surprised at the relatively low cost of either option. I do know the 648DX is in the works as well. Which was something else I considered. I am currently using a 645 MSI board, and have had fairly good luck with it, but I think some more voltage tweaking is necessary to get some better numbers. Of which I cant get from MSI's because of their weak voltage tweaks. I was impressed with the Albatron's 1.8 voltage changes. That would be awesome. I am though worried about the 845E chipsets lack of higher memory speeds. I would have to worry about how high my memory could go in order to take my chip higher because of ratios. I didnt know my P4 board choice would be so hard to make. The memory was almost a no brainer.

Just to help you out a little, of all the currently available DDR Boards the IT7 and the BD7 were able to push my Corsair3200 further than any other board.I got 170 fsb at 3/4 setting with a 2.26b, and Sandra bandwidth of 3500/3500 so I wouldnt concern yourself with the memory issues on 845E boards.Of course as i stated earlier that is with the Abit boards which dont disable that feature, or the E--x which doesnt overclock anywhere near as well.

So do you think the Abit BD7-II Raid would give the best overclocking DDR p4 motherboard for my P4 1.8A watercooled?

 

[Biosmaster]

No, in short.The best solution would be a IT7 as it has higher vdimm settings the BD72 will only give 2.7V which coupled with watercooling may not get your ram high enough.I would think that 3 gig is not out of the question with the latest 1.8a (Costa Rica pack dates of August are exceptional so try and source one), had three this week all hit 2.8 at 1.6v with Intel Cooling.My own is hitting 2.95 with a Swiftech MC4000T, the best air cooler there is, with a Pabst Fan not a Delta.So if you can stretch to it get the IT7 Max, should be awesome with watercooling.Get Corsair XMS3200 Cas2 Platinum and you should have a very fast setup.
