Slot A CPU wanted. 850mz or there about - not overclocked. Or advice on UK supplier.

Hi Robo,

Undertaking a search within this Forum for "Slot A” (without the quotation marks) should yield some threads that you'll find helpful in sourcing these increasingly rare processors.

Imo the ones really worth having are either the 700MHz 'Classics' (as their 'off-die' L2 Cache operates at 1/2 processor core speed – higher frequency parts have L2 cache that operate at greater dividers and thus slower speeds) and the best are the 1GHz Thunderbirds with 'on-die' L2 Cache that operate at the full speed of the core.

Hope this helps.

Let us know how you get on.

Cheers,

Hi Paul
I know of a supplier in the UK who has 'Classic' 700mz processors for sale.
From what you say, am I right in thinking that this processor will be as good as an 850 Thunderbird type?
My problem is this, having built my very stable system at just the wrong
time ( just at the change of processor types - sods law ) I am loathed to
throw out mb, memory, cooler and processor and replace with new but at the
same time my system ( on a 500mz Athlon processor ) will not cut the mustard when it comes to printing from the timeline in Media Studio Pro 6. Do you know if the 700mz will make that much difference or should I just start again with a new system?
Thanks
Robo

Hi Brian,

Here’s how I can best summarise this:

For the reason stated previously, the 700MHz microprocessor is the Athlon ‘Classic’ I would choose (and unsurprisingly the later 0.18um K75 variant above the original 0.25um K7 ‘Argon’ processors – fyi your 500MHz part is almost certainly one of the original K7 ‘Argon’).

However, I would choose *any* frequency Athlon with a ‘Thunderbird’ core over any K7 or K75 ‘Classic’ part.

So, no, a 700MHz ‘Classic’ would not “be as good as an 850 thunderbird type”

That said, imo a 700MHz ‘Classic’ is a very worthwhile upgrade from a 500MHz; I cannot say from experience precisely what difference it will make to your “printing from the timeline in Media Studio Pro 6” issue but it sure won’t be worse and will probably improve as with most other operations…

Bear in mind that you must check whether your mainboard will support any the processor types you are looking to install. You will need to check both the PCB and BIOS revision. Also check at AMD’s site, they have an excellent list of recommended and validated mainboards.

So in summary any ‘T-Bird’ above any a ‘Classic’ but check whether what you propose to install is supported (by your mainboard) before you buy it, oh and don’t overlook any thermal considerations, and especially if you are looking to use your existing HSF you will need a thermal interface material to place between processor and heatsink (as an aside I will not be using ‘Arctic Silver’ in the future, it is a real pig to work with, especially if, like I do, you need to switch different HSF; Shin-Etsu MicroSi G-749 Thermal Grease or the Chomeric THERMFLOW T725 Phase-Change Materials are *much* more manageable).

Btw what amount of system RAM do you have installed and what operating system are you running? Are you sure your processor is the bottleneck?

Let us know how you get on.

Hope this helps.

Cheers,

Thanks again for all the info.
fyi my system is as follows:
Gigabyte GA-71XE mb
256mb P100 ram
Pyro capture board
Riva 8mb AGP graphics
SB pci128 sound card
Two hard drives - one for video capture only, the other for system and programmes.Both well within the required speed.
Windows 98SE.

So far as I know, I've got all the latest drivers and have no conflicts. System stable and no drop frames on capture but direct print from timeline produces slight stutter at fade out/in ( not on any other transition )I've just assumed this was down to insuficient processor speed but would be happy for other sugestions.
thanks.
Robo
