Laptop Harddrive Speeds

Definitely worth the faster drive. Seagate (and probably others now) do a line with 8MB cache, and Hitachi now have 7200rpm 2.5in drives you might want to take a look at; the latter probably use more power but that may be OK in a desktop replacement. (A new 5400rpm will draw less power than an...

Contemplating my new XPC computer specs **PLEASE COMMENT**

Doing a lot of graphics work doesn't mean you need such a monster video card, all those gigatexels/sec are only really useful for gaming with textures, so back it off to something which doesn't have (or need!) a huge heatsink or a fan. Also, the 3200+ probably (almost certainly) will draw too...

Any AT'ers with the XP 1700+/1800+ T-Bred B's yet?

Guys, if you want to stress-test your systems, I'd recommend CPUburn * Use BURNK7 to see your Athlon's CPU temp go 7C higher than SETI or Prime95. (Sadly he's not done a customised P4 version.) Use BURNMMX to stress your Northbridge, most particularly the memory controller, and RAM. Once you've...

* * * Alpha PAL simple mod * * *

Was fiddling with my set-up this weekend. I've a Thunderbird 1333, Alpha PAL8045, Enermax 365xx. Previously I only had one fan, a Papst 8412NGL, the silent 19CFM fan, blowing on the HS, and the system ran warm (38C system, 60-63C CPU, under SETI@home). I turned the fan round, and the CPU dropped...

Need info on upgrading an older Athlon CPU

XP will run fine on that if you've enough memory; it's usable, as a pure desktop setup (no IIS or anything) on a K6-II 450MHz or even a P-II 266 as long as you've more than 256Mb memory, so a 650MHz Athlon will be great. The thing is - you can get a modern mobo for £50, 256Mb DDR memory for £20...

Why Overclock, why not just build it to that speed?

They (Intel/AMD) don't hold back, they just mark down their CPUs; if the market wants 1 3GHz CPU, 2 2.8GHz, 3 2.6GHz and 4000 2.4GHz and they've 1000 that pass the 3GHz test, 2000 that pass 2.8GHz test and the rest past 2.6GHz then they'll ship 1 marked as 3GHz, 2 2.8GHz, 3 2.6GHz and 4000...

Right, people here o'c but can't complain if they can't o'c much, any other (corp or private) customers don't o'c but would complain - rightly - if their systems didn't work 100%... so Intel/AMD feed the 99.9% of their market! :D

Overclocking beyond air?

53C/60C is normal with little or no case cooling, and is perfectly acceptable since even with under-read errors it's way below the tolerance. If you want to o'c, cool your case a lot; if you want your PC to stay quietish (i.e. not like Concorde taking off) don't and stay at stock speed/temp.

Most often it's the luser trying to overclock, like THUGSROOK said; after that it's cooling, then PSU, probably.

PII-300 vs. K2-500 how much difference

The K6 series only sucked on floating-point stuff - that's why a P-II 400 whips a K6-2 550 by half a day on SETI. Otherwise, they're not much different; for normal use I'd expect a K6-2 500 to be slightly faster than a P-II 300. The K6-III, K6-2+ and K6-III+ all have L2 cache on-die that the...

MS-6712 MSI board processor issues

Find the link or option for changing from 100MHz FSB to 133MHz FSB. The 2100+ expects 133MHz FSB and uses a 13x multiplier, but on a 100MHz FSB it'd run at 1300MHz, about the core speed of a 1500+ (actually that's 1333MHz). Some BIOSes work out the processor description from the core speed...

We haven't needed 6 PCI slots ever, except for the very few who stack their systems out with really smart stuff. Right now I've my modem, network, sound and SCSI cards in and there's still 2 free; with a more integrated mobo I certainly wouldn't need this many. That's leaving AGP aside. Given...

RAID 0-ing two 80gb WD 8mb SE's... what size stripe?

Given the drives' own large cache I'd say no less than 128K, probably 256K, as a starter; if you're doing video at high res or high frame rates then larger may be better, but to be honest it makes very little difference when the OS is cacheing multi-MB; sadly you can't dictate what the write...

Well IBM are big and worldwide, you're extremely unlikely to get another broken drive second time round - though having said that, if it's 1/x you get a duff one 1st time, if you do get a duff one then it's 1/x you get a duff one 2nd time. OK the likelihood of two duff drives is 1/x^2 but still...

What upgrade would give me the most boost until I do a complete overhaul this summer?

Going DDR would be good but you would need to spend more $$$. You should get quite a big jump out of just putting an XP2100+ or XP2200+ on, if you can get one fairly cheap, and make sure you put the latest BIOS on first so there's some chance of it being recognised. I wouldn't go any faster than...

Go for the SB51G, the newer revision of the Shuttle thing, it has the USB 2 and Firewire, and some digital audio options. And you can buy it now. The Dual CPU in One thing is Hyper-Threading, and is only available on P-4s of 3.06GHz and up. Read Anandtech's review on it.

High FSB = possible damage to other parts of computer?

The only things I ever heard of getting upset with a high FSB are the graphics card and the hard drive. The graphics card seems obvious, they tend to run fast & hot anyway (like your CPU but you're doing some serious cooling on it). I don't really know why hard drives complain; maybe the...

HyperThreading => even hotter? 3.06GHz+HT => 96W

We don't have 3GHz P4's in the UK yet... or at least not many, I can't find one! Whatever size the core is, the HSF has to shift an awful lot of heat. Still, glad to hear Intel have improved their stock HSF.

Which FCPGA Celeron is best bet for overclock?

If you can still find them at all, most of the late-fabbed 667-733 would be OK on a 100MHz FSB, though may need slight overvoltage. I haven't seen one for ages, though I dare say they're still about.

Jeez, 145 to 160 is a huge jump! You can't go from 1522MHz to 1680MHz in one go and expect it to work! Not on a Thunderbird, anyway, very few of them would hit much more than 1600MHz. Right, your default voltage should be 1.75V not 1.725V. Push your FSB as far as you can at stock voltage - I...

Yeah I'd agree not to bother with the PC3200 memory, as shown by Anandtech several times DDR400 really isn't necessary because it doesn't give much speed-up. Even DDR333 is barely any faster than DDR266 on an Athlon system, unless you're buying a 2600+ or 2800+ with the 333MHz FSB. Trade the...

Well, I wouldn't bet on it without a fan; OK compared to today's HSFs what you got on a Pentium was weedy, but then a classic P166 would only produce about 13W. "Only". I went and said it. That's still quite a lot of heat and if you only have a small heatsink, it'll still roast quick enough. Say...

Good micro-atx board for Intel 2.4B

Try the MSI MS-6526G. A firm I work for bought some of these recently, seems good to me. Right, don't go for the MS-6526GL, that only has 400MHz FSB support (that's why don't get anything 845GL based), but you probably *do* want the MS-6526G-L (yes, it's different) which has the LAN option.

Anyway, a 1600+ OC'd to the speed of a 2200+ will run pretty much exactly the same temperature as a real 2200+. Oh and there's really not that much of a real-life difference between a 1700+ and a 2100+, probably only about 10%. Try the OC again and see if you really care.

Duh, I must be missing a trick here. Your ClawHammer (out yet?) on NVidia CinForce (out yet?) with 400MHz DDR-II (out yet?) is too slow. Well I guess it would be, no mobo, no RAM, no CPU = no speed. PS. Maybe you need faster hard drives, them 160GB drives spin damn slow.
