Side effects of O/C 1.6 to 2.4 and beyond

What side effects I'm I likely to run into o/c a 1.6a?
I've been hijacked to upgrade from a friends PIII-500. I've decided on a 1.6a and either an Asus or Abit motherboard.
An Antec SX635 case. Arctic Silver II, stock retail HSF
Hoping to hit that magic 2.4 GHz
Recycling Gforce3 TI-500, Win98SE and hard drive.

He's on a really tight budget so every dollar counts. He also needs to spend the $$$ now before his wife gives birth.
If I get sound on the motherboard, will that hit me with a noticable performance hit? Does onboard sound o/c ok?
If not that route does a $35 sblive 5.1 mind being o/c?

How about NICs? Anyone see NIC having probs?

Whats the gaming performance between 2.5CAS memory and 2CAS memory other than 30-50% price increase?

I'd hate to have him spend $190 on Corsair 512M CAS 2 memory and find out my parts wont let me O/C or that $130 Samsung 512M CAS2.5 is only 5% slower....

What sound cards, NIC's, and CAS memory is everyone using to hit 2.4 GHZ?

Thanks!

Here is my recipe for success.
EPOX 4BDA
1.6A retail
Samsung PC2700

I run @ 2.4 GHz, 150 FSB, DDR400. The EPOX locks the PCI/AGP @ 33/66. It is the only 845 board that will allow you to run DDR400 @ 2.4 GHz. It also has the widest Vcore range 1.4 - 1.85.

Ash2Dust:

Asus P4s533 m.b., Samsung PC2700 DDR333 512 meg,Geforce4 TI4400 128 meg video card, Northwood retail 1.6a @ 2.4 on stock voltage using stock retail HSF. Antec SX 1040 w/ 400w p.s. I haven't upped the cpu voltage yet, to try for higher o/c's. I might if I upgrade the HSF to something better. I don't want to take the motherboard out just to attach a better HSF. Some of the better HSF attach threw the motherboard. I haven't found a good HSF that attaches just on the top of the motherboard.

Good luck with your project. It is really fun to o/c, as long as it doesn't induce heart attacks or strokes. The cpu 1.6a was on $118 at googlegear.

Well, if deciding not to go higher than 133FSB, I'm sure there'll be no side effects. It will give you a pretty nice performance increase with no stability problems. If you choose to go 2.4GHz, the side effects are possible, but not inevitable. With some adequate cooling and a little voltage increase the chip is very likely to be 100% stable.

Good luck!

I guess if I'm paranoid about the PCI/AGP daughtercards being overclocked beyond their specs I need to get a board that specifically allows locking their frequency (or better yet, allow choosing a multiplier divisor).
Seems as tho most people are comfy with the Samsung with the 2.5 CAS. I guess since there is a tight budget, it would make more sense. Just would be a shame to find out that 2CAS makes a noticable diff.
I've always been impressed with ASUS (they really are rock solid), liked the only ABIT board I've had, and have never touched an EPOX.
If only I had access to a pc parts warehouse, I would never come out.

old fart - You're running yours with a 3:4 memory ratio or something to achieve 400DDR with a 150 FSB and the memory your using is speced for 333?

I guess I should also ask what ratio/divisors/multipliers each mobo allows that helps really o/c and gaining performance.
Also I'm assuming I'd take a performance loss if I go with onboard sound

Thanks

Ive also ahve owned ASUS, ABIT, Giagabyte, SOYO (others). this is my first EPOX, and I'm very pleased.

Exactly. This is one of the things that sets the EPOX apart from others. It is the only 845 board that can do this.

I'd rather have the lock. PCI/AGP is 33/66 @ any FSB you use. End of story.
