Question Building new PC - What parts from my old PC can I reuse?

[Ancipital]

My old PC is dead (see: https://forums.tomshardware.com/threads/my-10-year-old-pc-wont-boot.3798688/ ) and I want to use its old RAM, power supply and GPU.
Will an old DDR3 work with a new mainboard for Ryzen 5/7?
I am not really interested in gaming.
I need a high freq CPU, not multi-threading, because my compiler is not multi-threaded yet.

My budget is around 1000 euros.

PS: after the first mainboard died, I purchased a used one (pretty expensive). It died 1 year later in the exactly same way.
So, I am somehow afraid to reuse the PSU. Maybe it killed the mobo...

Will an old DDR3 work with a new mainboard for Ryzen 5/7?

No. It's either DDR4 or DDR5.

I want to use its old RAM, power supply and GPU.

GPU can be reused.
Storage devices can be reused.

What PSU are you using?

budget? everything is how old?

> budget? everything is how old?
Hi
I updated my original post: the budget is about 1000 euro ($1100), but is only a number I came up with, because when I built my old system (12 years ago) I used the same number
Can be a higher IF necessary. But since I can reuse the GPU, 1000 should be fine.
_
So everything is 12 years old. Back at that time the system was STRONG... for 1000 euros

My priority is a high frequency CPU. My old CPU was compiling 1000000 sloc in under 25 secs. I hope that the new CPUs today have some other improvements, because the frequency didn't increased that much
Reason for which I kept my old system until it died.

As you can see, I built my last system 12 years ago, so I am a bit behind with what's new.....

AM5 with 8700G - 650 motherboard - 32gb ram - 650 psu gold - nvme 1TB
look for something like this and you will be much below 1000

Assuming you want to use all of it, reuse the gpu, and don't care about multithreading:

Your FX-8350 is very slow by today's standards. Particularly in single threaded performance.
Run the cpu-z bench and look at the single thread performance rating.
You should see a rating of about 232:
http://valid.x86.fr/bench/3ja7rs
By comparison, a modern $125 I3-13100 processor scores 678.
A similar amd rating would be a ryzen 5 7600. About $200.
Spending more gets you mote processing threads, but not that much more in single thread performance.


DDR3 ram is obsolete. DDR5 2 x 16gb would be about $60.

AA B760 based motherboard for Intel would be about $125.

PSU, case, and gpu can likely be reused.

 

[logainofhades]

I would not reuse any of it, except maybe the HDD and case. Current gen AMD APU's IGP is better than your GPU, while using a lot less power.

 

[Syntaximus]

Agreed, keep the drives and replace the rest.

That PSU is quite old (not even sure what model), it's time to replace that.
You can keep the case, but the front panel connections won't be modern (USB 3, C, etc).

 

[helper800]

Something like this while either reusing your old card or add in an AMD rx 6600 / 6500 xt, Intel a750, or an Nvidia rtx 3060/4060. Reuse your old drives as well:

RAM, storage, motherboard, PSU (as long as you didn't get a GPU that drew a large amount of power).

You can reuse your video card and HDD, this is almost 3X as fast as what you have. Enough storage you could probably use your HDD just for backup.
Smaller build.
EDIT you might need one fan splitter cable, about 5 bucks.

Note that the i3-14100 comes with a perfectly good stock cooler.

Perfectly cooled 50+ decibels if he's going to be using that 14100 for any real work, but that's just my opinion. I prefer to recommend 20-40 dollar coolers that are multitudes better at cooling and allow for more boosting at much lower temperatures.

Have you actually used one?
I can run the cpu-z stress test, and I can't hear the fan.
And the i3-13100 with all threads @ 4.28 is in a small lian li Q07 case that has no fans at all.

Honestly I cannot say that I have used these specific HSF that come with the 13th and 14th gens CPUs. My experience with stock HSF's is from 12th gen and before. Are they really worth their salt now?

Somebody posted this link: http://valid.x86.fr/bench/3ja7rs

Really cool! But does anyone know a similar comparison that shows the value of the CPU (performance / price) instead of performance? I think that would be a more realistic comparison.
_
In theory in my balance AMD and Intel are equal, but considering that Intel is in danger of taking monopoly over the x86 market, then my balance is slightly inclined towards AMD (at least until AMD will have a more equal market share).
So, I will rather go towards AMD.

 

[Ancipital]

PS: I don't trust much artificial benchmarks. I use now a much newer laptop with i5 7440hq.
CPU-Z says that this CPU is 146% (compared with the AMD FX reference 100%).
My compiler tells me something totally different.
These artificial benchmarks usually do a simple math operation (like prime numbers) in a tight loop. This can lead to very skewed results.

Here is an article on the new intel laminar flow coolers.
https://www.intel.com/content/www/us/en/products/docs/processors/laminar-coolers.html
I was referring to the RM1 cooler. I also bought a RH1 cooler on ebay.
It is not sold separately.
It is a beautiful piece of kit.
I used it on a i9-12900K in a itx case and it performed well enough for my purposes.
Probably not for most with I9 high end processors.

On a value point of view the RM1 is infinite if you divide the performance by the cost (zero)
It costs nothing to try it.

 

[logainofhades]

An i5 7440hq is way above any FX chip. I had a couple FX 8320's overclocked to match an FX 8350. They were terrible vs my i5 2400 and later 3570k.

Of course, the best benchmark is using YOUR compiler,peripherals and data.
In the absence of that capability single thread tests are what you have to go on.
I do not know what instructions CPU-Z uses, but I have to assume that they are reasonably picked.

Can you access the user forum for your compiler?
They may have more relevant comparisons.

Until now, the formula was "the higher the frequency, the higher the speed".
But I could try to find some statistics from people using a modern Ryzen CPU.
The compiler generates exe files that use the old CPU instructions, not the new ones because the generated executable have to be compatible with all existing computers (from Win98 to Win11). This might explain the behavior.
But all this is moot now. I repaired my old mainboard, it worked for a few days and now it died again. So, I need a new computer.
