Is their still hope for this chip? 1.6A

I got this chip 2 years ago with an GA-8SRX (SIS645) but because of the lack of dividers on this board I couldn't get it up higher than 2.1 (133fsb) with Crucial PC2100. Do you think an updated mobo (IS7) and Corsair PC3200 Value Ram will improve performance any? Or will I be looking at similar performance scores with the SIS645 board.
 
well...

considering the is7 has a pci/agp lock and 2.1 is pretty conservative, i'd say you can push that baby farther on a springdale board!

no harm in trying it on that board! 🙂

and 1.6A's were overclocking beasts!!!
 
Or you could sell someone the 645 motherboard + 2100 ram + 1.6A for 100 - 200 bucks and then instead of IS7 get an athlon 64 mobo by VIA or SIS 755 for $100 and 3200 Ram and use those 100 - 200 bucks you'll get and get yourself a new athlon 64 3000+

even if you get a new IS7 and new ram there is no guarantee you will overclock 1.6A past 2.6 ghz or higher. On top of the fact that it doesnt have HyperThreading you can decrease performance to equivalent of 2.4C.

so soon you'll want to upgrade again... but with Athlon 3000+ you get P4 3.2 perfomance in games or higher right away and general performance higher than athlon 3200+ xp and majority of p4 3.2 as well.

In your case even if you sell the 1.6 + mobo + ram for a measly $100 (i am sure you can do better) you'll just need to add $120 (and that new mobo and ram you wanted to buy anyways) but the system will be wayyyyyyyyyyyy faster and upgradable in the future

Ahk!! Decisions, decisions!🙂

I think your post went a little south.....

Let me correct some stuff....

1) Your assumptions of 3000+ equalling p4 3.2ghz is pretty much in gaming only and in other areas the muscle of the p4 shines in encoding, etc....I think you are being very vague.....3000+ cannot equal a p4 in a majority of apps if you get beyond 6 game test in a review od 12-14 tests overall....3000+ has no answer from the performance of HT....

2) My 1.6a hit 2.74ghz with 1.71v actual and temps were quite reasonable 52c loaded....It can be done and if you tell us the packing date I can give you a better idea of what those chips were averaging...early 1.6a's right of the gate were hitting 133fsb or 2.13ghz very consistently....Later 1.6a's were getting to 2.4ghz a bit more regularly and right before they phased them out they were making 2.8ghz p4's and thus some 1.6a's were lucky to get to 2.6-2.7ghz range....

3)Sis 755 mobos from early results (IE like the ECS) appear to be real stinkers when it comes to ocing...

4) He doesn't need a 3.2ghz chip to beat a 3000+ he can save loads of cash by getting a 2.4, 2.6 or 2.8c chip and have a good cahnce of 3.2ghz and maybe a shot at a bunch more...I hit 3.5ghz with my 2.4ghz which gives me a whopping 1168fsb....My 2.4@3.2 performed better then my 2.6@3.2 so I would say if there was a stock p4 3.5 or even just the new 3.4 oc'd to 3.5ghz I would have the edge and be more situated to that of a 3.6ghz p4 stock....

5) Lets not forget that even to this day most p4c reviews (please go reread them) rarely use HT enabled apps (besides the extremely bashed tomshardware) and therefore when we really start comparing these systems beyond gaming apps how much faster is it really...How much faster does the p4 get when it does more (multitasking)...Who knows I will probably have to buy one for us to find out since no one wants to seem to look at it....

yes it will be an excellent upgrade.
 
Hey, thanks for the replies & info everyone. I thought I'd take advantage of upgrading my mobo and ram since my aunt is in need of a basic rig for email/and playing movies for the nieces and newphews, but I don't have enough for a cpu right now. Otherwise, I would have taken more consideration into changing platforms (again😛).

Pack Date : 01/16/2002

Thanks again Duvie.
 
Hmmm...Both thugs and I had 5/2002 chips and were both in the 2.6 to 2.7ghz range.....I would say that constitutes an earlier p4 1.6a so I would likely say that 2.4ghz may be a stretch but my 1.8a with a pack date of 12/01 did it so good luck....I think 2.2ghz is more likely....

That's fine. We'll see by Thursday what difference this upgrade can make. Has it already been two years? With the rate I've been building comps (and the rate Intel has been moving) it only seems like last month I put in that combo.

isnt 1.71 actual volts really pushing it???
 
Yep!!!

I first put a 1.8a on a Asus sis645 mobo back in Feb 02.....That chip did 2.4ghz w/ 1.65v....

Got a 1.6a in May 02 and tried an Epox 4BDA i845d mobo and got that chip to 2.74ghz w/ 1.71v.....moved to a 4g4a+ mobo but did not better the oc (some compatability issues)....

Held onto that chip until March 03 when I got a 2.4b that did 3.24ghz w/ 1.6v on a Albatron i845PE mobo....

Moved to p4c with hyperthreading in Nov 03 with a 2.6 that only did 3.2ghz at 1.58v on a newer Abit IC7 i875mobo....


wasn't happy so I upgraded to a 2.4c that does 3.5ghz w/ 1.58v on same mobo.....


Probably hang on until I see a good price 1mb cache prescottt chip that will do 3.6 to 3.7ghz air cooled...

You would think but the earlier p4a chips actually handled the vcore better....Many of us have noticed with the advent of the b and c chips that cpus get less after default then what they used to get and prime95 with the b chips was a bit more iffy getting stability past 1.6-1.65v...that is why many of us started to change our toon and recommend to more then 1.65v...


What you actually don't know is that I ran that chip at that same point for 10 months and then sold it to a guy in MI who is still running it at 2.7ghz last I check at 1.68v....So that chip has lasted now for 19 months...I don't think the 1.7v hurt it too much....

NOw I wouldn't run that now but that also may have more to do with the tremendous speeds and subsequent heat that would be involved....
