I am the soon to be the proud owner of a brand spanking new P4 1.5. Even better the Government is buying it for me. However, amoungst all the jolity, looms an i845 SDR chipset. I mean saints preserve us, the P4 couldn't have been more effectively castrated. So it seems to me the thing to do is to buy one of them there brand spanking new SIS 645 chipsets with that oh so lovely DDR 333.
First question: When will they be released?
Second question: How effectively can you overclock a P4 1.5 using a stock HSF. Or is there a better way?
I'm not an intel user but why don't you use a chipset that supports rdram? Ray says that it's not much more expensive that ddr and it's performance is above ddr's? Just a question.
One thing, i845 supports socket 478 Northwood right? With the core improvements in Northwood it should perform much better then the current cpu "willimetta" for i845.
By first upgrading to Northwood (jan) and see how it will kick, before buying new ram and mobo altogether might be a good id'e.
But I agree Sis645 DDR333 PC2700 looks sweet
BTW, Will i845-D chipset support DDR333 PC2700 like SIS645 DDR333?
Say it with me. W-I-L-L-A-M-E-T-T-E. Willamette. It's the river that cuts Portland, OR in half, east/west. I used to drive over it every day on my way to work.

No, the last info from Intel showed that it would only support PC1600. No PC2100, PC2400 or PC2700.

On the other hand, what is the best Socket 478 i850 board at the moment, I mean the Asus P4T is damn good, but is only in 423 imlementation.
Abit TH7-II or Asus P4T-E

On Willamette yes this might change slightly with Northwood thats what i mean. Still we don't know what the improvements will be to Northwood but i have a feeling that they will increase the preformance of the i845 also. ex. i845 Northwood vs. i845 Willamette.
Ofcourse i850 DRDRAm will outpreform i845 beacuse of bandwidh PC133 SDRAM can only provide 1.06GB/s of memory bandwidth.
DDR p4 will also outpreform sdram p4. The "best" would probably be Northwood P4 DRDRAM PC1066 with 533FSB Sis645 PC2700 with Northwood also very intresting.
Asus P4t and MSI 850 Pro2 preformed very good (possible the fastest P4 0.18 boards) There is the Asus P4t-E and MSI 850 Pro5 (MS-6545) for socket 478 no reviews yet. Raystonn made a list the other day with P4 i850 mPGA 478 mobos....
If i already had a i845 system i would try the Northwood first and see how it's performance is on i845 and then get a new mobo if i wasn't satisfied. I mean you don't lose anything (that is if you had planned on getting the Northwood.)
My 2cents.

What you say is true. However the publisised upgrades to Northwood will be a 512 Kbyte L2 cache and such tricks as hardware pre-fetch (I think). But all this will at the most give the Northwood a boost of c. 15%. This hopefully should keep the P4 competitive with the Athlon XP which has really done very well in benchmarks. I don't see what Intel plan to do with the i845 that could really make up its performance deficeit without implementing PC 2700 DDR solution or maybe a duel channel DDR set-up, because, as we all know, the P4 really does love its memmory bandwidth. Plus Northwood is not going to be released until early next year, (maybe Raystonn can correct me on this) and I'm an impatient SOB.
..hehe well it's slightly disappointing that the Northwood will be released in Januari (i think) instead of this coming November. I agree with you, if you are looking for a top performing P4 then you will have to get RDRAM or DDR ram board for it. I can't see that Northwood will change that in favor of the i845sdram
Check this out! <<The second DDR chipset from Intel will be i845 version with the integrated graphics core. This solution aka Brookdale-G is expected to arrive in the middle of 2002.>>
<< The third product, we would like to mention, seems to be the most interesting of all, especially as it is for the first time that Intel reveals its details. This chipset will have some codename starting with āSā and is scheduled for H2ā02. Its key feature will be the dual-channel PC2100 DDR SDRAM interface. In other words, this solution will be provided with 128bit memory bus featuring 4.3GB/sec bandwidth, just like NVIDIA nForce. Actually, it is all very logical. The newcomer should also support new Pentium 4 CPUs working with 133MHz FSB and 533MHz Quad Pumped bus, which bandwidth will also make 4.3GB/sec. This way, the use of dual-channel DDR SDRAM interface will let Intel develop a well-balanced Pentium 4 chipset with DDR SDRAM support. Intel is also going to implement AGP 8x support there, and due to the new ICH4 South Bridge this product will acquire USB 2.0 and SerialATA support as well. >>

What are you going to be using the system for?? It seems to me that having a 20% slower system should not matter for the things most folks use their system for. Who is paying for the better MB? If it is comming out of your pocket I'd take what they gave me. A 1.5GHz is damn fast even - 20%. I've got a 1.3 w RD800 and the only things that make me wait are the modem and video conversion.
Yeah, but no you know anything about the overclocking tolerances of the 1.5 GHz? I just want to know a ball park figure off what O should be able to get out of the chip.
Woah, is it that bad?
I know that the 1.5 P4 is actually cheaper than the 933 PIII. So I thing I should get one of those Abit TH7-II boards and 256 MBs of RDRAM (shudders) . So then guess I should O/c as much as I can until the Northwood makes a showing. Whats the record for Overclocking the 1.5 Ghz part (with standard air cooling, no water coolers, pelties, just standard HSF)?
