Saw this for sale for just over £100 and went for it to (maybe) finally replace my ageing Northwood (in sig). The chip is retail and has only been used to see how well it performs and the seller assures me it boots into windows at 3.75hz (250x15) at stock volts. I should hopefully have the chip by the weekend, did I do the right thing?
Considering that new, they cost $180 USD, or about 90 GBP (plus additional tax and whatnot) No, it wasnt, considering you could get a new one for a little more, or possibly less
Yeh, Americans always forget that we pay alot more for hardware over here. It just doesn't work the same way as the exchange rate.
We probably pay closer to 125% of the price in USD ... The number, not the cash value. Something priced at $1 will probably cost £1.25 here.
Well I finally got around to installing it, and so-far-so-good - 3.91Ghz (260x15) at default voltage. I think my ram (4 sticks) is still stopping me getting past 260mhz to get 4Ghz, even with a vcore of 1.5v+. I'll have to try with just 2 sticks again, as I reached 280mhz with my old CPU. Maybe I'll need a better cooler first though, with 1.5v this Prescott runs much hotter than my old Northwood at 1.65v. The Alpha 8942/Delta just about keeps it under 50degC under load! Some quick benchies: Sandra (2004) Sandra (2004) Sandra (2004) 3DMark 03 3DMark 05 Edit: Added pics of the cpus, new & old: The new Prescott on the left and the trusty (very-)old 2.8b (133/533) Northwood engineering sample (previously at 3.57Ghz, 255x14) on the right. After 2 years or so in my PC it's finally time for her to put her feet up and break out the Horlicks.
Unbuffered Sandra memory score: Temps (according to MBM and Sandra) idle are 37-38C, and I haven't seen it above the high 40's under load yet.
Temps are v.good! - you watercooling? Your memory speed is low though - ive got stock 939 systems pulling 2-300 faster than yours, and stock DDR2 systems pulling 4k+ :/ Can you tighten your ram timings??
That is a great OC. Drool at mine! Intel Pentium 4 520 (LGA775), stock: 14x200=2800, now: 14x267=3730 stock cooler 59C load AS Ceramique Paste.
Sorry if my temperature statement is confusing, it's in the high 40's, i.e. 48C+ under load, with the 81019 bios reading with Sandra and MBM. Cooling is with air - my old Alpha 8942, AS5 and Delta 80mm SHE on full chat. Unfortunately, at 2.85v this Adata ram will not run any tighter than 2.5,4,4,7 at 250mhz or above. And at 260mhz I had to set it to cas3 too . Tightening any/both of the "4" values results in instant no-diggedy. I may be looking around for replacement ram soon (2x512MB sticks instead of 4x256MB), Can anyone recommend any inparticular? Nice overclock there too Sabeeh. Your temps are higher though. It could be the cooler, but what bios do you use and what s/ware are you using to report the temps?
I bet watercooling that babe.. 4.2Ghz easy (using divider if mem can't go higher of course) Vgood piece i'm running my D0 Philipines on water 4.16Ghz stable, abit mobo no-vmods 1.47vcore (at full load)... must do that vdrop mod sometime B
