[SOLVED] Optiplex 745 upgrade

[Aleks4k]

Okay i have Optiplex 745 Mini Tower and i going to buy new cpu and gpu and also change ram so i wondering if someone can tell me next:
Can this graphic card
GT 1030 Silent Low Profile 2G
Fit with this comp i will add Q6600 Proccessor and i got nice power supply
Please answer me if someone know thanks!

Mini tower isn't restricted to low profile GPUs though.

What's your usage goal for this dinosaur?

What's your upgrade budget?
What country are you shopping in?

 

[ChumP]

Can you also provide us with the exact model of that PSU you've got?

 

[Aleks4k]

My power supply: Seasonic SS-500ET 80Plus Bronze
Graphic Card which i need to add: GIGABYTE GV-N1030SL-2GL GeForce GT 1030 2GB GDDR5 Silent PCI
I got like 150$ and i buying in Serbia also i want just to upgrade pc to can play league and maybe CS:GO

The short answer is yes. But a Q6700, or QX 6700, QX6800 would be better, and the Q6600 can't be overclocked in that one like the later Optis.

A built out Opti745MT would have a QX6800 SLACP CPU, 8GB DDR2-800 low density x64 RAM, and "ZOTAC GTX1050 Mini" GPU.
The D9729 heatsink fits, and the whole fan assy. can be replaced with a Dell NC466, or DG168 Delta AFC1512DG 150x50mm fan. This is a very quiet, very powerful fan. 1.8A. 256cfm.

The next step would be an overclock using Throttlestop 6.0 software to 3.45-3.73Ghz. Heatsinks on the VRM MOSFETS help. Only the QX CPUs can do this.

The ZOTAC Mini is the only 1080P GPU that drops right into that computer. The 4GB Ti will work best most of the time, but may have issues with a few memory intensive games/benchmarks.

Notice the short PCB, and 2 slot wide cooler but single slot bracket. Unfortunately people are asking about twice what they're worth.


A QX6700 is dirt cheap but the B2 stepping runs hot and slower. 3.2 to 3.45 GHz is about all.
A better GPU if you're wilingl to do a slight mod is the MSI GTX1060 3GB OCV2

The bracket can be removed and cut in 1/2 due to no connectors on the 2nd slot side. trim the plastic to be even with the end of the PCB at the other end. The 3GB won't have any RAM capacity issues.

This will require a PSU swap. The 375W Dell PSU form the BTX Mini towers will drop right in, and has all the correct power rails for this old computer. Precision T3400 models will work.

Overclocking Dell BTX Computers

Why overclock a Dell? Because they're there. Millions of them in fact. Just about every Dell, HP, Gateway, Acer, etc. Intel computer for almost 10 years was a BTX. Many of them are being sold now as refurbished computers for less than you can buy an operating system license. BTX was originally a...

Ah yes, the Optiplex 745 was a BTX board. So yes, you'll need a card with a single slot rear bracket (like the one william p linked) or a complete single slot cooler, OR with the intention of cutting off the upper half of the bracket on a dual slot card....

Many ppl said that Q6600 is best for this pc and lastest i didnt saw anywhere that i can put even QX6800 or Q6700

Thanks for answering so you think i can add this Gpu at this comp?

 

[william p]

I didn't see your post with the budget while I was writing that. The Seasonic PSU should be OK as long as the 5V. rail has enough power to match what the Dell PSU provided. The QX6700 is probably within your budget. The QX6800 SLACP are $60 or more.
The SL9S5 QX6800 isn'y any better than the QX6700 so avoid them.
A GTX750 DDR5 is a better GPU. You have to avoid any that require a UEFI BIOS.
I've modded 2 slot single fan versions to fit.

 

[Aleks4k]

I just want to ask another question
I will add 4X2 ddr2 800 ram and A400 120GB ssd so with this graphic card and Q6600 cpu and new power supply will everything works fine withouth overclocking? Also can i use old Processor cooler for the new one?

I cant put GTX750 on my comp also single fan versions of 750 are really rare on Serbia thanks

That's just going by what Dell listed back in the day. You will also see a 4GB RAM limit too.
You can see them running here and the CPU scores. There is no Q6800 all are QX.
https://www.userbenchmark.com/System/Dell-OptiPlex-745/3949
I have personally tested a QX6800 SLACP and 8GB DDR2 in an Opti 745 to 3.45GHz. The latest Dell BIOS supports it.
The Dimension E520 in my sig. and the link to CPUZ is the same era BTX system with a better 4 phase vs. 3 phase VRM setup.
An X6800 is another option for single thread games. Maybe 3.73Ghz then?

 

[william p]

The Q6600 will work just fine. The cooler depends on which one you have. The aluminum one for the 2 cores won't work.
The Copper fin one is OK up to about 3Ghz. The D9729 is an old PentiumD/Pentium4 cooler and can handle 130W CPUs. With the fan mod it can run any overclock. They don't cost much. The heatpipe cooler, and big fan can both be found for around $10 each since they're just old obsolete junk for their original purpose. Once you get an unlocked CPU the overclock costs $0.

 

[tennis2]

GT1030 = GTX750.
The GTX1050Ti is the best bet here.

If the bios can update to support a q9400 or 9550 I’d go for that instead the performance is a lot better with the 9000 series

Currently i got Intel Pentium D CPU 2.80GHZ and cooler for this processor so do you think this cooler will support new processor i will have to buy new one?

I would like to try this combination but i cant find where can i buy this processor there are no this processor on my country avalible even second hand

I have some of this stuff sitting around. I'll PM you.

That's an old Pentium4 based MB. 266 fsb and 65nm Core2 is all it can support. With an unlocked CPU and overclock it can keep up with those. But it will be burning some Watts to do it.
